Describe the solution you'd like
I often find myself wanting to move a weakaura or group on an axis. The nudge buttons help but I get rsi from all the clicks needed for larger position changes.

The magnetic alignment helps, but requires a relative element (or a positioning helper)

Describe alternatives you've considered

Shift + Click the nudges to move by 10px
