Added keyboard event listener to allow deleting selected layers using the Delete or Backspace keys when the layers panel is focused. This improves accessibility and user experience.
Eliminated tabindex and keydown event listener from the CanvasLayersPanel container. Keyboard interactions are no longer handled directly in this panel.
Changed UI text in CanvasLayersPanel from Polish to English and removed the add layer button and its logic. Moved and improved the ResizeObserver logic in CanvasView.js to update both the canvas and layers panel positions dynamically based on the controls' height.
Added tabIndex to the panel container to allow keyboard focus and attached a keydown event listener to forward keyboard events to the main interaction handler. This improves accessibility and enables keyboard-based layer deletion from the panel.
Centralizes layer movement logic in CanvasLayers with a new moveLayers function, supporting both up/down and drag-and-drop reordering. Updates selection logic in Canvas to only trigger updates when selection changes, and improves event handling in CanvasLayersPanel for more responsive selection and drag operations. Removes redundant moveLayersToPosition method in favor of the new unified approach.
Introduces a new CanvasLayersPanel component for managing layers visually, including selection, renaming, reordering via drag-and-drop, and deletion. Integrates the panel into the main Canvas and CanvasView, synchronizes selection and state changes, and adds logic for duplicating layers and debounced state saving. Moves IndexedDB state saving to a Web Worker for better performance. Also sets default logger level to DEBUG for improved diagnostics.
