Yeah, Maptools can do all of that, but I just prefer no grids. I think the maps look better without them and I play old school 2nd ED and don't need them. If I do need to have a grid on a map I'm making, I try to make it as subtle as I can. Of course, that's just my preference, I know many people use the grids. So, make the map the way you want it to look, and if there happens to be a map with no grid as well, then I will be a happy mapper!
