    <summary>Efficient Loader</summary>
  
- A combination of common initialization nodes.
- Able to load LoRA and Control Net stacks via its 'lora_stack' and 'cnet_stack' inputs.
- Can cache multiple Checkpoint, VAE, and LoRA models.   <i>(cache settings found in config file 'node_settings.json')</i>
- Used by the XY Plot node for many of its plot type dependencies.

    <summary>Ksampler & Ksampler Adv. (Efficient)</summary>

- Modded KSamplers with the ability to live preview generations and/or vae decode images.
- Used for running the XY Plot script.   <i>('sampler_state' = "Script")</i>
- Can be set to re-output their last outputs by force.   <i>('sampler_state' = "Hold")</i>
