Feature Requst - Adding arrow key functionality for adjusting avatar position by pixel

On the desktop app, when setting the User Avatar or Server Icon position, it would be nice to be able to use the arrow keys to adjust the placement a pixel at a time. It can sometimes be annoying trying to center or otherwise finely adjust a position within the allotted circle.

It seems like a simple and intuitive quality-of-life feature. After all, that's what arrow keys typically do in image prompts or editors.
