It would be nice to be able to give doors and windows a name plate with options to be visible to only the GM or to GM and players. In the edition of Dungeons & Dragons I play, the quality of locks has an effect on a character's percentile chance to pick it. Masterwork locks, for example, give a -50% handicap to pick locks. A nameplate would be useful to convey this information immediately to the GM without having to create a note on the GM layer.
