To save time in removing supports for a 3D print, I am suggesting "tapered" support, so that by the time the object's support reaches the underside of the needed support, the support structure itself is smaller so that is it easy to remove. Seems, as it stands now, supports are the same diameter at the build plate and up to the needed underside of the printed object.
**** Also, within Cura, a needed tool: A way to measure (from point A to point B), just like in any CAD program. There's always a need to verify/need to measure any part of an object to be printed. The only way now is to rotate the object against the build plate within Cura to get an "idea" of the measurement, but it's not really accurate enough.
