sticks to a previous promt and cant change it

When using Firefly its very annoying that you cant change the "subject" after working on an idea... asking for a style or subject makes the AI to stick to it, and even if you change the subject or want to try e different approach, it maintains opened the "Session" and wont let go the first idea or style.

There should be a way to make "projects" so we can change the prompt and get a completely different result, or "re-open" a project to keep working on it in a different day or even month later (like in my case today).

And if that exist... well, you really need to hire a new user interface designer...
