This feature request is mostly related to cards.
As of now, there is no easy way to create circular or round tables for more odd numbered games since rotation snaps to 15 increments.
I would like to see an option where cards use the players handzone as the basis for the rotation snap increments.

Basically, if a persons handzone had the angles {0,21,0}, it would offset the rotation snap degrees by 21.
This would make oddly shaped boards much easier to create, since you would not be locked to 15,30,45 or 90 degrees.
