Journey Mode: Low and High steps range with preview and click-through iterations

[mchaker]

Feature description:

It would be extremely helpful to have a "journey mode" where a user could specify a Low and High steps range, and a batch size (or sub-iteration-amount, with batch size 1 to save memory).

Then, starting at the Low steps range, the first iteration would be generated.

The user would click on one of the images, and that would be used as the seed (or img2img input?) for the next iteration.

Then, the steps would increase slightly (at some increment specified by the user per iteration?)

Then in the same UI, the next iteration would appear. The user would select their favorite image. The process repeats until the max steps value is used to generate a set of images.

Thoughts?
