(some are hidden behind other nodes you have to collapse them)

FLUXinator (STD/GGUF/NF4) img2prompt, controlnet, F1depth/canny, Detailer, SUPIR

<ul><li>rebuilded and fixed (e.g. sampling restarts when nothing has changed (seed, prompt etc.))</li><li>removed nf4 support (doesn't work with loras so...)</li><li>it's also possible to use the load image group, bypass the sampler and do the upscale/detailing on the loaded image</li></ul>
