Alrighty - the way I see it right now we're only able to paste individual objects into canvas objects, right?
It'd be awesome if we could simply paste a whole layer into a canvas object. Imagine a multiplayer game where player1 is on layer1 and player2 is on layer2. Then you split the screen with 2 canvas objects and paste layer1 into the left canvas and layer2 into the right canvas, done.
