I think I would be able to add that, also your project is saved every move, either when you move some clip on timeline or on canvas/player

Automatic saving seems like the best option. Then you can always just re-open the tab. Undo is better than confirmation.

FWIW a few people fly around the web with persistent cookies and localstorage disabled except for selected sites -- once the tab is closed, the data is flushed, and re-opening the tab won't restore it. I'm one of those people. I recognize that this is entirely a "me" problem and don't expect anyone to change the way their software works to accommodate this behavior. Just raising a flag.
