Is there a free animation software with an undo button?
I have a windows 11 computer, which is touch screen. Whenever I draw, I tend to flip it around, so it functions like a tablet. In the past, I've been using Adobe Fresco for animation because it has an undo button that does not require the use of the keyboard, but it's been getting laggy to the point that I can barely draw long form animations. Every other 2D animation software I've looked at doesn't have one, which makes it extremely difficult for me to animate. I'm also poor as hell, so I can't afford better animation softwares either.
It doesn't have to be great quality or have to be capable of supporting a great FPS, since I tend to use 6-8fps for most of my stuff, but I just need smth with an undo button and I don't want to keep playing this game of trial and error.
I've googled and looked around, but everything I can find is either stuff I have to buy or is generally extremely difficult to use (steep learning curves n stuff), which is why I came here.
