I’ve tried a bunch of animation apps but this is the one I keep coming back to year after year. I have one request is that the undo feature stay relevant through frame changes. As I’m thinking about this though I can see how it would be a hassle. Each frame would have to be considered an individual project probably. Otherwise, say you saw something wrong through the onion skin but you have already done a bunch of work on the next frame. You’re have to undo everything all the way back to whatever it is you want to change. Unless undo’s stayed tied to each frame so they wouldn’t affect after frames when used. And that seems like it would require, like I said each frame to be its own entity or project. I don’t know, just thinking and typing. If there was a way to keep undo’s to be frame specific that would be a big help. Otherwise love the app!
