What is the enhancement in mind? How should it look and feel?
If enabled, tooltip would show also, how much time passed till plot owner was last seen on server. The same that can be achieved using /seen command om Essentials.
Also, there may be an option to show this only for selected players (admins). This can be achieved by checking is user with IP on list, and is he logged in game.
Why? On our server (I saw it on may others) there's policy that if player is not logging in for 20 days, his plot may be deleted (to slow down map growth), it's done manually - we are not removing nice, complete buildings, and looking for them manually is waste of time.
