You know what other program where you can Animate: Krita
Well I barely tried animating with it, but I do use an animation file as a virtual notepad for quick sketches, where each frame is like a new page. This format is really useful for quick iteration.
Iām not a 2d animator by trade, but the animation feature set seems adequate.
It can be worse than my real software of choice for 2d, blender. but Iām also a weirdo, who sometimes refuses to do things properly.
There is also opentoonz, but I have even less experience on this one.
Tldr: Have you heard of our lord and savior, Krita.
