As the title say, i think an hotkey that while being held, move the mouse to the location you are looking at (same location that is used for vr-hotkey selection) would be great.
I know you can use the mouse offset setting but thats always on and needs you to move the mouse manually to match the cursor with the location you look at.
A feature to only move the mouse to where you are looking at when a key is held would be incredibly useful when a mouse based UI is visible, would save the need of mapping a gamepad joystick to mouse movement just for those scenario.
