Exiting news, congrats on the launch!
A minor feature request for the positive extrude, for when you get to it.
Kekit has view and mouse direction based constraints for any translation tools, so you don’t need to press X/Y/Z or their equivalents for plane based constraints. It does so with TT-tools:

Notice that in Kekit, this system works also for Context Extrude, which extrudes Vertices/ Edges/ Faces depending on the mode you are in. I understand you would be reluctant to rely on a third party addon for this, but I definitely think it is a good opportunity to integrate both for general extrusion tools. It saves a quite a few inputs in the long run 
Also, how feasible would it be to automatically run a Machin3tools cleanup after a PunchIt operation? As in integrate the two in one tool?
