Is there a way to make the nudge faster? Maybe I'm just dumb and can't figure it out, but if I need to move annotations or text that I've already written, the only ways to do it are either the nudge tool, which is good for tiny distances but painfully slow for anything else, or cutting and pasting, which is really inaccurate and time-consuming

Select the annotation with the arrow tool and you can just drag it.  At least that's what I do in my Android tablets, I guess is the same for Windows?
