Hi!, When I'm animating, I miss a feature global_offset that Harmony, Maya or Blender have, and that is being able to adjust some selected frames already animated and give them another position (example attached: https://animbot.ca/tooltips/en/#global_offset).
For Onionskin it would be great to have the function of motion trail tracking by means of a line, and focusing on some point of the object, it is more efficient to adjust trajectories compared to green and red shapes (example attached: https://animbot.ca/tooltips/en/#motion_trail_style), I know that you can adjust a point as an image, but there is nothing better that comes by default.
In the timeline I usually use bookmarks in animation software like Harmony or Maya, this is useful to have a guide when one action ends and when another ends (example attached: https://animbot.ca/tooltips/en/#time_bookmarks_visibility).
It would also be good to implement animation layers, which would allow, once our animation has been created, to be able to manipulate the keys through said layers, which would allow us to add more animation without damaging the current animation.
Thanks for your time!
