This came about because of a nasty crash I had last night, but it made me think this might be useful:
If you're in design mode, and you switch to operate mode, could there be a prompt to save your workspace if you haven't already?
I know, I know "save early, save often" but sometimes you forget and you lose 2+ hours of work when you try to test something out. A simple reminder might not hurt. Maybe could be enabled or disabled in preferences or something.
Thanks!
