Viewport Navigation Gizmo and rotating camera to UV editor & Image editor

Why do we need this?

The rotating camera is important for painting or drawing, as it's more convenient in certain situations.

And the coordinate gizmos (X,Y)(U,V), why in these views?

1. It's a visual aid for beginner artists new to the 3D world, especially in UV view.
2. It allows you to align the view at 0, 90, 180, and 270 degrees.

This may not be essential, but my past self would appreciate it.
