Pros: it's harder to delete pages which means it is hard to accidentally lose progress. I like the redo button. The size tool is way less laggy. In long animations, the play button plays the animation at the frame you're on, it helps when you want to see how the end of a anim is like so you don't have to watch the entire thing. Cons: it's harder to delete frames so you can't delete long parts of a animation that you're not proud of. The blue eraser is gone and so is the pen. I erased a part of something and then it was stuck to my screen and it was not erasable.
