With this add-on you can easily toggle on/off the name labels for all objects in the scene at once.

To have a better overview at all objects, its often necessary to see all their names or find them by your custom descriptions, especially when there are plenty in the scene. With one click you can now show all names as an UI-Element at the origines of every object, or turn them off all together, if not needed any more.

Color and font size for the text can be customized.
