This is a minor one but a bit of a nuisance, which I always trip over. For pretty much every piece of software that I have on my Mac the expected behaviour is to scroll the window horizontally with the left or right swipe of the mouse.

Except for Cartoon Animator. For some reason I can scroll the timeline vertically with the up/down swipe but not horizontally! I don't know the reasons why the developers made it that way but I find myself tripping over it pretty much every single time, so I have to drag the scroll bar, which when you are in the middle of the process is a nuisance. The shortcuts that I found: Option-Drag sorta does the job but you still have to press and drag and I don't find it very convenient, whereas CMD-Swipe doesn't work very well for me - it sorta jumps to the beginning or to the end, when I really only need to move a few frames.

Anyways, one may say that it is too minor of a deal, and it is, but I think it would really be nice to be able to move the timeline horizontally with a side swipe.
