I'd love to see the possibility of having separate keyframes for each point (a bezier point + its 2 handles) on a path deformation, maybe having the option to have a single key for all vertices (like it's working now) or separate, or maybe another kind of path with separate keyframes for its deformation.
Right now the workaround to handle a curve with separate keyframes is to assign a bone to each point you want to control, but if you also want to control its handles, you'd need a lot of bones and the rig can become too complex, besides, you don't have control over the way the handles change the curve (by pressing Alt you can set an acute angle, but you have to keep it pressed to make it work, unlike other software, the mode will reset to the default if you unpressed Alt).
The way I handle this is by using both features: bones to control some points and deformation keys to control the handles when needed, but I think this approach increase the complexity of the rig.
Ahh, and I'd like the Offset tool to work with deform keys, I find paths extremely helpful to animate secondary actions but I can't use one of the best tools Spine has to offer to that purpose.
