For img2img, if I could generate of one those masks that matches up to the various objects in the image, that would help a lot. Otherwise, I need to draw them or make them myself every time. Would be great as a feature in automatic1111's UI to auto-generate maskable regions to use in stable diffusion.

Also, I'd be interested in removing backgrounds and then re-generating them inside of different contexts to feed into dreambooth, i.e. to remove an object that is a part of a subject from its context and put it in a different one. For example, if I wanted to make a prosthetic arm that sits on a table, or if I want to make fried rice but remove the plate from the background and give it additional possible backgrounds instead. This will probably break dreambooth instead of doing what I want, but if it works, it's going to be some awesome witchcraft that lets me turn one object into a very different one.

I could just as well run it on my computer locally, but I do work on that machine and don't like using 100% of my GPU processing in the background.
