I often have to redo the large chunk of the auto-generated supports - usually because some object faces need to be support free and yet the only realistic part orientation requires that face be in the auto-support “firing-line” so to speak. It would save so much time if groups of supports could be removed in one go, instead of having to laboriously pick them off one by one.
A drag-box select would be fine, but a lasso would also be cool.
It would also be nice to be able to change the contact point size of a group selection.
