Exceedingly simple Data Broker panel which displays the state of your Nameplate toggle. A single color-coded letter is displayed, speficially:

N = Nameplates off (grey)
F = Nameplates on for friendly targets (green)
E = Nameplates on for enemy targets (red)
B = Nameplates on for both of the above (blue)

Possibly useful if, like me, you tend to turn plates off in towns and then forget what their state is just before a pull or whatever, and find the behavior of the toggle button very hard to discern at times without targets nearby as a reference point.

If you want different colors or longer words or whatever, just crack open the .lua file and edit the obvious strings in updateObject().

Of course, you will need a Data Broker display addon of some sort for this to do anything.
