+
+### 5. Documentation and Initialization
+- **EventManagerDocs.md**: Comprehensive documentation
+- **eventManagementInit.js**: Initialization and global handlers
+- **Features**:
+  - Global escape key handling
+  - Modal state synchronization
+  - Error handling
+  - Analytics integration points
+  - Cleanup on page unload
+
+## Application States Tracked
+
+1. **bulkMode**: When bulk selection mode is active
+2. **marqueeActive**: When marquee selection is in progress  
+3. **modalOpen**: When any modal dialog is open
+4. **nodeSelectorActive**: When node selector popup is visible
+
+## Priority Levels Used
+
+- **250+**: Critical system events (escape keys)
+- **200+**: High priority system events (modal close)
+- **100-199**: Application-level shortcuts (bulk operations)
+- **80-99**: UI interactions (marquee selection)
+- **60-79**: Component interactions (model cards)
+- **10-49**: Tracking and monitoring
+- **1-9**: Analytics and low-priority tasks
+
+## Event Flow Examples
+
+### Bulk Mode Toggle (B key)
+1. **Priority 100**: BulkManager keyboard handler catches 'b' key
+2. Toggles bulk mode state
+3. Updates EventManager state
+4. Updates UI accordingly
+5. Stops propagation (returns true)
+
+### Marquee Selection
+1. **Priority 80**: BulkManager mousedown handler (only in .models-container, excluding cards/buttons)
+2. Starts marquee selection
+3. **Priority 90**: BulkManager mousemove handler (only when marquee active)
+4. Updates selection rectangle
+5. **Priority 90**: BulkManager mouseup handler ends selection
+
+### Model Card Click
+1. **Priority 60**: ModelCard delegation handler checks for specific elements
+2. If action button: handles action and stops propagation
+3. If general card click: continues to other handlers
+4. Bulk selection may also handle the event if in bulk mode
+
+## Remaining Event Listeners (Not Yet Migrated)
+
+### High Priority for Migration
+1. **SearchManager keyboard events** - Global search shortcuts
+2. **ModalManager escape handling** - Already integrated with initialization
+3. **Scroll-based events** - Back to top, virtual scrolling
+4. **Resize events** - Panel positioning, responsive layouts
+
+### Medium Priority
+1. **Form input events** - Tag inputs, settings forms
+2. **Component-specific events** - Recipe modal, showcase view
+3. **Sidebar events** - Resize handling, toggle events
+
+### Low Priority (Can Remain As-Is)
+1. **VirtualScroller events** - Performance-critical, specialized
+2. **Component lifecycle events** - Modal open/close callbacks
+3. **One-time setup events** - Theme initialization, etc.
+
+## Benefits Achieved
+
+### Performance Improvements
+- **Reduced DOM listeners**: From ~15+ individual listeners to ~5 coordinated handlers
+- **Conditional execution**: Handlers only run when conditions are met
+- **Priority ordering**: Important events handled first
+- **Better memory management**: Automatic cleanup prevents leaks
+
+### Coordination Improvements
+- **State synchronization**: All components aware of app state
+- **Event flow control**: Proper propagation stopping
+- **Conflict resolution**: Priority system prevents conflicts
+- **Debugging**: Centralized event handling for easier debugging
+
+### Code Quality Improvements
+- **Consistent patterns**: All event handling follows same patterns
+- **Better separation of concerns**: Event logic separated from business logic
+- **Error handling**: Centralized error catching and reporting
+- **Documentation**: Clear patterns for future development
+
+## Next Steps (Recommendations)
+
+### 1. Migrate Search Events
+```javascript
+// In SearchManager.js
+eventManager.addHandler('keydown', 'search-shortcuts', (e) => {
+    if ((e.ctrlKey || e.metaKey) && e.key === 'f') {
+        this.focusSearchInput();
+        return true;
+    }
+}, { priority: 120 });
+```
+
+### 2. Integrate Resize Events
+```javascript
+// Create ResizeManager
+eventManager.addHandler('resize', 'layout-resize', debounce((e) => {
+    this.updateLayoutDimensions();
+}, 250), { priority: 50 });
+```
+
+### 3. Add Debug Mode
+```javascript
+// In EventManager.js
+if (window.DEBUG_EVENTS) {
+    console.log(`Event ${eventType} handled by ${source} (priority: ${priority})`);
+}
+```
+
+### 4. Create Event Analytics
+```javascript
+// Track event patterns for optimization
+eventManager.addHandler('*', 'analytics', (e) => {
+    this.trackEventUsage(e.type, performance.now());
+}, { priority: 1 });
+```
+
+## Testing Recommendations
+
+1. **Verify bulk mode interactions** work correctly
+2. **Test marquee selection** in various scenarios
+3. **Check modal state synchronization** 
+4. **Verify node selector** positioning and cleanup
+5. **Test keyboard shortcuts** don't conflict
+6. **Verify proper cleanup** when components are destroyed
+
+The centralized event management system provides a solid foundation for coordinated, efficient event handling across the application while maintaining good performance and code organization.

+# Centralized Event Management System
+
+This document describes the centralized event management system that coordinates event handling across the ComfyUI LoRA Manager application.
+
+## Overview
+
+The `EventManager` class provides a centralized way to handle DOM events with priority-based execution, conditional execution based on application state, and proper cleanup mechanisms.
+
+## Features
+
+- **Priority-based execution**: Handlers with higher priority run first
+- **Conditional execution**: Handlers can be executed based on application state
+- **Element filtering**: Handlers can target specific elements or exclude others
+- **Automatic cleanup**: Cleanup functions are called when handlers are removed
+- **State tracking**: Tracks application states like bulk mode, modal open, etc.
+
+## Basic Usage
+
+### Importing
+
+```javascript
+import { eventManager } from './EventManager.js';
+```
+
+### Adding Event Handlers
+
+```javascript
+eventManager.addHandler('click', 'myComponent', (event) => {
+    console.log('Button clicked!');
+    return true; // Stop propagation to other handlers
+}, {
+    priority: 100,
+    targetSelector: '.my-button',
+    skipWhenModalOpen: true
+});
+```
+
+### Removing Event Handlers
+
+```javascript
+// Remove specific handler
+eventManager.removeHandler('click', 'myComponent');
+
+// Remove all handlers for a component
+eventManager.removeAllHandlersForSource('myComponent');
+```
+
+### Updating Application State
+
+```javascript
+// Set state
+eventManager.setState('bulkMode', true);
+eventManager.setState('modalOpen', true);
+
+// Get state
+const isBulkMode = eventManager.getState('bulkMode');
+```
+
+## Available States
+
+- `bulkMode`: Whether bulk selection mode is active
+- `marqueeActive`: Whether marquee selection is in progress
+- `modalOpen`: Whether any modal is currently open
+- `nodeSelectorActive`: Whether the node selector popup is active
+
+## Handler Options
+
+### Priority
+Higher numbers = higher priority. Handlers run in descending priority order.
+
+```javascript
+{
+    priority: 100 // High priority
+}
+```
+
+### Conditional Execution
+
+```javascript
+{
+    onlyInBulkMode: true,               // Only run when bulk mode is active
+    onlyWhenMarqueeActive: true,        // Only run when marquee selection is active
+    skipWhenModalOpen: true,            // Skip when any modal is open
+    skipWhenNodeSelectorActive: true,   // Skip when node selector is active
+    onlyWhenNodeSelectorActive: true    // Only run when node selector is active
+}
+```
+
+### Element Filtering
+
+```javascript
+{
+    targetSelector: '.model-card',      // Only handle events on matching elements
+    excludeSelector: 'button, input',  // Exclude events from these elements
+    button: 0                          // Only handle specific mouse button (0=left, 1=middle, 2=right)
+}
+```
+
+### Cleanup Functions
+
+```javascript
+{
+    cleanup: () => {
+        // Custom cleanup logic
+        console.log('Handler cleaned up');
+    }
+}
+```
+
+## Integration Examples
+
+### BulkManager Integration
+
+```javascript
+class BulkManager {
+    registerEventHandlers() {
+        // High priority keyboard shortcuts
+        eventManager.addHandler('keydown', 'bulkManager-keyboard', (e) => {
+            return this.handleGlobalKeyboard(e);
+        }, {
+            priority: 100,
+            skipWhenModalOpen: true
+        });
+
+        // Marquee selection
+        eventManager.addHandler('mousedown', 'bulkManager-marquee-start', (e) => {
+            return this.handleMarqueeStart(e);
+        }, {
+            priority: 80,
+            skipWhenModalOpen: true,
+            targetSelector: '.models-container',
+            excludeSelector: '.model-card, button, input',
+            button: 0
+        });
+    }
+    
+    cleanup() {
+        eventManager.removeAllHandlersForSource('bulkManager-keyboard');
+        eventManager.removeAllHandlersForSource('bulkManager-marquee-start');
+    }
+}
+```
+
+### Modal Integration
+
+```javascript
+class ModalManager {
+    showModal(modalId) {
+        // Update state when modal opens
+        eventManager.setState('modalOpen', true);
+        this.displayModal(modalId);
+    }
+    
+    closeModal(modalId) {
+        // Update state when modal closes
+        eventManager.setState('modalOpen', false);
+        this.hideModal(modalId);
+    }
+}
+```
+
+### Component Event Delegation
+
+```javascript
+export function setupComponentEvents() {
+    eventManager.addHandler('click', 'myComponent-actions', (event) => {
+        const button = event.target.closest('.action-button');
+        if (!button) return false;
+        
+        this.handleAction(button.dataset.action);
+        return true; // Stop propagation
+    }, {
+        priority: 60,
+        targetSelector: '.component-container'
+    });
+}
+```
+
+## Best Practices
+
+### 1. Use Descriptive Source Names
+Use the format `componentName-purposeDescription`:
+```javascript
+// Good
+'bulkManager-marqueeSelection'
+'nodeSelector-clickOutside'
+'modelCard-delegation'
+
+// Avoid
+'bulk'
+'click'
+'handler1'
+```
+
+### 2. Set Appropriate Priorities
+- 200+: Critical system events (escape keys, critical modals)
+- 100-199: High priority application events (keyboard shortcuts)
+- 50-99: Normal UI interactions (buttons, cards)
+- 1-49: Low priority events (tracking, analytics)
+
+### 3. Use Conditional Execution
+Instead of checking state inside handlers, use options:
+```javascript
+// Good
+eventManager.addHandler('click', 'bulk-action', handler, {
+    onlyInBulkMode: true
+});
+
+// Avoid
+eventManager.addHandler('click', 'bulk-action', (e) => {
+    if (!state.bulkMode) return;
+    // handler logic
+});
+```
+
+### 4. Clean Up Properly
+Always clean up handlers when components are destroyed:
+```javascript
+class MyComponent {
+    constructor() {
+        this.registerEvents();
+    }
+    
+    destroy() {
+        eventManager.removeAllHandlersForSource('myComponent');
+    }
+}
+```
+
+### 5. Return Values Matter
+- Return `true` to stop event propagation to other handlers
+- Return `false` or `undefined` to continue with other handlers
+
+## Migration Guide
+
+### From Direct Event Listeners
+
+**Before:**
+```javascript
+document.addEventListener('click', (e) => {
+    if (e.target.closest('.my-button')) {
+        this.handleClick(e);
+    }
+});
+```
+
+**After:**
+```javascript
+eventManager.addHandler('click', 'myComponent-button', (e) => {
+    this.handleClick(e);
+}, {
+    targetSelector: '.my-button'
+});
+```
+
+### From Event Delegation
+
+**Before:**
+```javascript
+container.addEventListener('click', (e) => {
+    const card = e.target.closest('.model-card');
+    if (!card) return;
+    
+    if (e.target.closest('.action-btn')) {
+        this.handleAction(e);
+    }
+});
+```
+
+**After:**
+```javascript
+eventManager.addHandler('click', 'container-actions', (e) => {
+    const card = e.target.closest('.model-card');
+    if (!card) return false;
+    
+    if (e.target.closest('.action-btn')) {
+        this.handleAction(e);
+        return true;
+    }
+}, {
+    targetSelector: '.container'
+});
+```
+
+## Performance Benefits
+
+1. **Reduced DOM listeners**: Single listener per event type instead of multiple
+2. **Conditional execution**: Handlers only run when conditions are met
+3. **Priority ordering**: Important handlers run first, avoiding unnecessary work
+4. **Automatic cleanup**: Prevents memory leaks from orphaned listeners
+5. **Centralized debugging**: All event handling flows through one system
+
+## Debugging
+
+Enable debug logging to trace event handling:
+```javascript
+// Add to EventManager.js for debugging
+console.log(`Handling ${eventType} event with ${handlers.length} handlers`);
+```
+
+The event manager provides a foundation for coordinated, efficient event handling across the entire application.
