Have a setting to allow us to customize our UI (It doesn’t seem like grabbing works, but I can try again later).
Login Screen: Have it so you can set the distance/height. Sometimes the login screen (particularly on relog) is so close to my chest that without moving, it is hard to select login (since delete is right there as well)
Map/Log: Allow us to bring the map and log closer to us (or further) as it can be hard to see sometimes.
Menus: Similar to the other suggestions, let us reposition the menu for personal ease of use.
[Solved] Item positions: Especially for sitting players, as sitting results in some items being below the ground, allow us to adjust our item positions. Maybe we want some of the items more out of the way or in a more reachable position.
