### Nodes:
<!-------------------------------------------------------------------------------------------------------------------------------------------------------->
<details>
    <summary><b>Efficient Loader</b> & <b>Eff. Loader SDXL</b></summary>
<ul>
    <li>Nodes that can load & cache Checkpoint, VAE, & LoRA type models. <i>(cache settings found in config file 'node_settings.json')</i></li>
    <li>Able to apply LoRA & Control Net stacks via their <code>lora_stack</code> and <code>cnet_stack</code> inputs.</li>
    <li>Come with positive and negative prompt text boxes. You can also set the way you want the prompt to be <a href="https://github.com/BlenderNeko/ComfyUI_ADV_CLIP_emb">encoded</a> via the <code>token_normalization</code> and <code>weight_interpretation</code> widgets.</li>
    <li>These node's also feature a variety of custom menu options as shown below.

         <p><i>note: "🔍 View model info..." requires <a href="https://github.com/pythongosssss/ComfyUI-Custom-Scripts">ComfyUI-Custom-Scripts</a> to be installed to function.</i></p></li>
    <li>These loaders are used by the <b>XY Plot</b> node for many of its plot type dependencies.</li>
</ul>

    <summary><b>KSampler (Efficient)</b>, <b>KSampler Adv. (Efficient)</b>, <b>KSampler SDXL (Eff.)</b></summary>

- Modded KSamplers with the ability to live preview generations and/or vae decode images.
- Feature a special seed box that allows for a clearer management of seeds. <i>(-1 seed to apply the selected seed behavior)</i>
- Can execute a variety of scripts, such as the <b>XY Plot</b> script. To activate the <code>script</code>, simply connect the input connection.

    <summary><b>Script Nodes</b></summary>
    
- A group of node's that are used in conjuction with the Efficient KSamplers to execute a variety of 'pre-wired' set of actions.
- Script nodes can be chained if their input/outputs allow it. Multiple instances of the same Script Node in a chain does nothing.

        <summary><b>Noise Control</b></summary>
    <ul>
        <li>This node gives the user the ability to manipulate noise sources in a variety of ways, such as the sampling's RNG source.</li>
        <li>The <a href="https://github.com/shiimizu/ComfyUI_smZNodes">CFG Denoiser</a> noise hijack was developed by smZ, it allows you to get closer recreating Automatic1111 results.</li>
            <p></p><i>Note: The CFG Denoiser does not work with a variety of conditioning types such as ControlNet & GLIGEN</i></p>
        <li>This node also allows you to add noise <a href="https://github.com/chrisgoringe/cg-noise">Seed Variations</a> to your generations.</li>
        <li>For trying to replicate Automatic1111 images, this node will help you achieve it. Encode your prompt using "length+mean" <code>token_normalization</code> with "A1111" <code>weight_interpretation</code>, set the Noise Control Script node's <code>rng_source</code> to "gpu", and turn the <code>cfg_denoiser</code> to true.</li>
