You are right, but I want to just point out "regression", with easy solution. The metric grid worked like this before, while not perfect it is better then nothing. Recently I was working on big 4 layer board, with metric grid (because of mounting & heatsinks) and having no Ctrl-G was .. well annoying :-).

Is it possible to do this for imperial units (mils) now? For me (opengl version) imperial grid is always changed by 5mils also.

gpcb-menu.res.in calls SteValue(Grid, ...), and this changes the grid by 5mils by default. I think that it would be logical to add another action only for grids, am I right? I already trying to add thermals to SMD pads - not easy (and I'm not a software person anyway), but possible.
Thanks for Yours comments,
