The inventory type functionality could come in handy, especially for games where they have a magic system or something similar, it could take some of the headache out of having multiple invisible characters and viewing their inventory, and just have one inventory box with applied filters.
I personally don't have a use for it (right now), but it could be useful, just not to a majority.
