Is there a way to use the Align and Distribute feature, like under the menu arrange on control points used in a motion path?
It seems this is disabled for Motion Paths, but I was half expecting it to work since we do allow distribute/align tools for Vector Shapes (which are basically the same under-the-hood). I've added an item on our todo list to allow for this.
In the meantime, you can workaround by copying the motion path into a vector shape, performing the align/distribute arrangements, then pasting back onto the motion path. Please see this section of the documentation for how to copy/paste back between the formats:
