Is there a way to remove all the objects on a layout (I'm doing a Level Editor and want a "Delete All" button/sprite) without restarting the layout? Or do I have to individually "Destroy" each object with its own event?
I don't think so, but you can put all your sprites in a family, all you buttons in another, etc., and destroy each family.

Put all the Sprites within a family and make a Destroy Button.
On Button Pressed -----> All Sprite Family Destroy
All Sprite Family Inside Layout
Should work, I think.
If you can't use families then on event
destroy object
