Thing is though, it DOES snap, but not to the same snap points as in the VAB. When I tried to attach a small solar panel to a small fuel tank, it did seem to snap like it was set to Octa-snap. When mounted in the first place, the panels were attached using a quad-snap. Maybe it's just that the game engine "sees" that small fuel tank as an object with eight sides, and the mods "snap" is not using VAB type snap, but in fact object side snap. Would be awesome though to have the same amount of precision when attaching stuff so you don't loose your vessels symmetry.
