Reset move gizmo to object face or geometry After rotation has been applied to an object, is there an easy way to re-align the move gizmo back to the object geometry?
NOTE : All gizmos in the image are LOCAL, not global. A shows the desired result, B is what I have now.
Its quite easy if you are using the latest blender versions. After you have rotated your object and applied the rotation, simply go to &quot;Options&quot; and select Affect only - origin.

Now you can simply rotate your Origin using either the Rotation tool or Rotation Shortcut &quot;R&quot;. 
After you are done rotating the origin you can exit the Affect only - Origin mode.
Note : You can not only rotate the origin, but also can Move the origin and also use Snap features.
