Hello Michael,
is it possible to add in a scaling option that can be set to reduce the amount of scale from farther away in version 4, like a taper effect? Or possibly being able to control the extrude by also adding an option to extrude less when farther away from the point of extrusion if selected. Another 1 it would be very cool once setting up a lined section if you could possibly hit a button that says all corner section turn into a 90 degree rounded instead of hard edge. Just some ideas that would save a lot of time when modeling. If you need more details on this I will show some examples of what I mean.

Take care.
