It's an awkward question and I don't know how to word it right. I'm working on a small object about 10cm across. When I want to inset a circular face, I can't do it to the degree I want because Blender sees that I'm zoomed in all the way and so huge mouse movements only make a tiny inset. And because the maximum inset distance is reached when my mouse cursor is over the center of the circle, the space I have to move the mouse is limited. That means I have to either inset many times before I get to the desired amount or I have to zoom out a huge way back but then I can't see what I'm doing.
So the question is, is there any way to increase the amount of manipulation per distance traveled with the mouse during an inset operation, so I can use circular insets on a small scale?
