I had already made a suggestion along these lines, but I would like to make it a little more specific.

Create a simple separate animation sequence (If you can call, at least 10 points for just one smooth walking sequence, simple ;) ), such as walking, running, jumping, gesturing, sneaking, etc. Finalize it as a template! to copy it in over and over, or maybe as a "loop" "time event" and just define the orientation and path the character has to take in space instead of setting each time key individually over and over.
So to say, nothing different than how it works in any video ga

This would speed up the work immensely, it would of course be a hit to be able to use such a "loop", projects like figures across the board, with slight corectures for Planti or Digigrade feet.
Such a loop could then also be shared more easily with others.
