Daz: that's odd... if I fire it up grid shows up in the reference object box automatically at the bottom of the NEX panel. Did a quick test mesh and it worked for me.
Yeah can't get grid snap going on at all. By the way, the fact that simply saving a texture in PShop and Alt-Tab-ing back into Maya updates all the textures without having to touch anything is worth its weight in gold alone.
Not having any integration issues. Looks to be what I would call seamless in fact. A question ( and I had a look on the forums but couldn't find an answer) Is there a way to get the quad draw points to snap to the grid as you lay them out? Say you weren't using the tool for retopology purposes, but for building something…
