I need to ability to go back to a previous screen or see a history of my work.

I need the ability in Firefly to 1) go back to the previous screen, and 2) recover a history of the image generations and prompts I have worked on. This is extremely frustrating as I try to learn the tool. I click on one button that doesn't have any tool tips or directions, and then I end up on a screen that doesn't allow me to go back to the previous screen. I have lost a lot of work and don't see why I would keep using this tool if it's so easy to lose all of that work. If there is a way to see my history or go back, it should be more prominent and easy to find. You also need a help button with context for the current screen. The UI is way too minimal.
