Hi Brian, there isn't currently any way to display the grid over top of everything instead of underneath it.

It shouldn't be hard for me to add that when I start working on new features again. It will be a few weeks or maybe a month before I'll be ready to do that.

In the meantime I have added this to the wiki wishlist: http://moi3d.com/wiki/Wishlist so that I can keep track of it.
