Since I have plenty of Gp, I frequently change my point allocation; however, doing this is a pain.

May I suggest the following addition in addition to the 1 point allocation as currently enabled.

minus all points : takes away all points from that skill

max points : allocates min(12, remaining points) to a skill

This would be a lot faster than manually changing the points one by one. Moreover, it wouldn't have to save each and every time I want to move points.
