Ye, I'd seen that.
What I meant was without selecting the edges that parallel the loop direction. Only selecting the edges perpendicular to the direction you're intending to slice, for quads.
It'd help for tri's too. It'd allow add vertex and slice mid point edge selected to mid point edge selected.
The program seems to be half way there already, in that, we can edge extrude . Its restricted to selecting only one edge on a poly though and cant select more than that without selecting all the poly, whether tri or quad. If we could select two on a quad or two on a tri, we'd be in business.
