Many animations are missing the ending options, usually those in the comic format but it applies to others as well, e.g. Pyra.
Also, I think it would be better if instead of a full list of all animation variations we could have clothing separately to reduce the size of some lists, so first there could be either a smaller list or a button to toggle the clothing preceding the list of animations with the selected clothing. Maybe add an "all" option by default to show all animations.
It would be nice if we could have proper controls like play and pause, as well as looping and reset for endings (or make it possible to reset it by selecting it again rather then switching between animations), besides the speed buttons. Probably also a zoom reset option.
