Pierre, is multiple surfaces relatively high on "the list"? 

I have my surface successfully showing some family relationships, and I want it specifically for this and I don't want to alter it.

I would now like to have another surface. I'm making a reference for my thumbpad and ; I've tried cardview and mapview for it, and it's pretty good, but I think surface would be better. 

Is the plan to have an infinite amount like the grid, or a finite amount?
