Remember the state of the Editor when exiting

When I exit the app, give me the option to save the current state of the Editor (which images are loaded) and load those back when I restart the app.

Note, a more advanced version of this could introduce the notion of “Projects”, where a Project is a set of Editor images. It’s powerful, but it adds one more bit of complexity to the app, and I always want to keep it as simple as possible. I’m curious if users would prefer “Projects” or are ok with just saving the current state of the Editor at any given time.
