Incriment snap distance settings?

When using Blender I like the snap to increments for my first grab and move functions - my primary build base is a grid pattern - the issue I have with it is that its only allowing me 1 meter increment snaps - would be real handy if we could have a setting that allows us to choose our preferred "jump distance" - like 0.5 or 0.25 etc rather than having to go to far and manually back up or key in the distance manually in "N - tools" or shift to try to "sneak up on the distance I want" lol (I am forever replacing keyboards because I lose the shift key - often on both sides)

Anyone else think this is going to help us less experienced and beginning users?
