PROBLEM
The hitbox of the axis gizmo is much smaller than the one in the 3D viewport which lead to many misclicks. The gizmo in the 3D Viewport you don’t even have to hover with the mouse directly above it, but the gizmo in the UV Editor does not even react when you hover on the tip of the arrow.
My brain is smart enough to have muscle memory about where to click on the arrow, but it fails every time when I switch to the UV Editor.
Since I am a new user I cannot upload any footage.
SOLUTION
Make the hitbox of the axis gizmo in the UV Editor the same size as in the 3D Viewport.
