Now we have so many options for extrude and revolve...
I propose a new option for extrude from distance to distance (asymmetric) where both distances can be to the same side. Like distance from face in behaviour, but without having to use an existing face.
The same thing for revolve, but with angles.
It can be implemented by changing the behaviour of the flip button so it only affects one dimension, and having two flip buttons, one for each dimension.
