It's be great if there was a detection block that would sense when the project ended, this would be great for resetting certain things for multiplayer games, simulations and games that have save files.
It's kinda like the “when project starts” block, except it happens when the project it stopped.
I know I'm not the only one here with this idea, right?

this has been talked about on 1.4
while it could be very handy
(if you made a program that stores data you could instruct the variables to “self-destruct”)
the point of the stop button is to stop everything.
so i'm not sure if this will happen
