This X button will not ask you if you want to save when you click it, it just automatically will close whatever project your working on. I accidentally clicked this and lost 4 hours of work
I know i should of saved more often but I got really into my game-making and lost track of time.
Might also be a good idea to implement an Auto-Save x minutes feature like is seen in Hammer.
