Hi Brian.

1) Do you mean to say "Add Points", as inserting knots into the surface? Or you referring to "growing" a selection (as in "Shift+" in Hexagon)? I think adding points is a very different thing entirely... Or maybe you did mean that? :\

2) Are you requesting to grow the point selection by a distance in both U and V from the first selected point? Such a function is handy but not as elegant as a dynamic selection radius which updates as you change your input.

I think your requests might need a bit more explanation...
