Currently the animation timeline feels very undercooked in comparision to the other features of the app. Not sure if there is an overhaul in the works for it at all, but either way, features that would be greatly appreciated are:
Animation FPS - more of a QoL request than anything but being so close to the edge of the application border, if you have it fullscreened you will find that your click-drag associated slider to the left border clamps very quickly due to the distance from the monitor edge. An infini-scroll would be preferable in this use case, rather than the slider range being defined by monitor size.
Inserting a new blank keyframe currently appends a keyframe to the end of the timeline, forcing you to have to manually drag-place the blank keyframe where you would like it to be in your timeline. The same goes for creating a new duplicate keyframe. Very inconvenient and sometimes frustrating!
Animation folders, for grouping. Colour keying for both standard layers + folders and animation layers + folders would be incredibly helpful for organising complex work. as seen in Photshop for example.
Step forward a frame/Step back a frame/go to end of animation/go to start of animation.
Step forward/back, rewind, step to end are quite essential when animating in order to jump through frames and check animation steps. I see that step forward/back are implemented which is awesome, however I’d still like to see a jump to end and rewind to start.
Loop Play toggle and loop play select - absolutely essential when creating looping animations of any kind, however the ability to toggle it is also very desirable, as is the ability to select a portion of the animation timeline to loop.
Timeline Zoom - being able to zoom in and out on the timeline when working on larger animations is really helpful to be able to see all of the anim frames, or focus in on one specific area.
Decoupling timeline layers from canvas layers - being able to delete a timeline layer should not require that the canvas layer be deleted first. It can very easily clutter up the timeline.
Hope these are worth considering! I really love the application and am a huge fan of the project, so I’d love to be able to use it more often for creating animation work!
