LDB-based button to show/hide all hovering character names (players, pets, npcs, etc.) with one click.
You can assign a hotkey to this action through Key Bindings in the Game Menu, under 'Broker Show/Hide Names' (addon key bindings are at the bottom of the list). I'd suggest 'Alt+x', or something similarly close to your UI hider hotkey.
You need to have a LibDataBroker display addon like ChocolateBar for the scarab icon and text to show. The hotkey works whether or not you have a display addon, as long as you take the time to actually set one (see above).
