It seems that Apple doesn't provide a way to rename desktops from the default "Desktop 1", etc. Renaming desktops would be great for my workflow.
Does anyone know how to do this manually or with a third-party app?
If an application is in full screen mode in a given space, that space will have the application's name under it when it is displayed via Mission Control (and you put your mouse cursor over the desktop). Otherwise, I do not believe that there is a way to rename them.
