Everytime I create custom bevel profile adding points to a curve I have to manually increase number of vertex count for beveling or add a driver, but what if it will be from out of box automated. After I add new point to a curve the number will increase +1 and the opposite case. I remove point and number will decrease -1.
Of course if I want more subdivisions I will have another option like in subdivision modifier to smoothly subdivide.
P.S. What about snap to grid points or lines and of course grid should be subdivided to snap bevel points with Ctrl.
