Enable User editable supports

I think it would be very useful to be able to edit supports manually.   either by selecting and deleting supports, or by stretching new supports between two selected points.    the base support or raft should also be editable.  I think a draw and erase function on the support base would be fantastic.

Thanks, Travis! We’ve heard this one a lot and it’s something we’re definitely aware of. We’re looking at different strategies for solving these kinds of concerns.
