Mesh Tool - A Mesh Editor

Set pivot: Awesome.
UV Window: Cool. Makes sense. =)
New mesh from scratch: Yeah, with out using an existing mesh. Just a mesh from nothing that you can add to a folder you want somewhere in content browser when done or right when you start is basically what I am thinking.

On Extruding edges: Way too much to do haha. I think I will just straight extrude the edges with move tool and bridge edges where needed or collapse / weld verts where I want hehe.
