Maybe you can already do this, but when you select an object and use the arrow keys to "nudge" it, it does move. This is ok, but it would be nice to be able to set what value it moves with each nudge.
What would be even better would be to have a "Large" and "Small" nudge valve, where pressing the "Shift+{arrow key}" would move it the large value, where as just an arrow key would move it the small value.
And yes, you should be able to specify both of those values.
