this looks pretty cool! are there some videos to show how the tools work? is that a target weld in your tools? your target weld work like in max? does your edge loop button allow you to select poly loops as well as edge loops...or could we request a poly loop button?
In maya you select edge loops by double clicking them, and for poly loops you click on a poly, hold shift, and double click on the poly next to it. You can also select a partial loop this way.
