Live Flip Animation

[Cubouse]

Detailed description of your suggestion

A tool to toggle doing what "Flip Animation" does automatically at every keyframe edit.

Similar in principle to the mirror modelling tool. There could also be a toggle per group, to disable flipping some keyframes.

It would be very useful for walk cycles and the likes; it is currently a bit tedious to edit one side, delete the "old" keyframes of the other side, then click the Flip Animation tool, click the offset option, and finally confirm.
