For general modeling, when I need to create fillets, I have to select edges, and hopefully have clean edges, in order to create a fillet. What I think would be a fantastic addition is a fillet based on how machinist would fillet a part. Currently, I run an axis down the center of what I want to fillet, and then I draw a triangle, then I sweep-cut it in order to get my machined fillet. I feel this is something that could be really well automated, as well as much more accessible to those that create super complex geometry, and recognize that the edge will have be filleted. It also can allow us to clean up screw thread so that they are actually 3D printable and usable.
