I don't think I've tried it before....but, it's like..in the new editor, you can have layers, which like, for example, if you're drawing a furry being tweened, you could draw the head on one layer, the hands/arms on another, unless you wanna move each hand uh m, then, you'd have to paste the frames onto each other, and uh yeah btw frames are different than layers you add layers on the bottom, not the top using the new editor, though the old one, you can't tween, but you can animate hope that kinda helped,,, idk
