Extension: ComfyUI Ultimate Auto Sampler Config Grid Testing Suite

ComfyUI Sampler testing & benchmarking tool for testing Stable Diffusion samplers, schedulers, CFG scales, prompts, img2img denoise values, and LoRA combinations. Features infinite-canvas dashboard image grids with virtual scrolling that can handle thousands of images, multi-model comparison, automatic resume on interrupt, and real-time visualization. Test entire checkpoint folders, stack multiple LoRAs, generate random seed variations, and export optimized configs. Includes fullscreen mode, keyboard navigation, smart filtering by parameters, and one-click regeneration workflow. Perfect for sampler output optimization and hyperparameter tuning.
