Greetings again. I have a suggestion: a keybind, which will act like Ctrl+Z, but for frames (as reverse F). Number of reverses can be limited. It would be very, very useful. Thanks for your attention.
The only problem is some reactions are irreversible, like if a particle is deleted by VOID, how would it know what happened before?
The solution would be to save every frame, but that would be very expensive memory wise...
Yes, but making number of reverses limited will save the situation.
What I usually do is just right click on an empty space before unpausing/pressing f. I guess it's limiting in that you have to do it in advance, but it means you can watch an explosion multiple times in different views, for instance. Though it will be a bit different every time.
