Quest Tracker with filter features? (by zone?)

[Jynks]

I seem to have a ton of quests and the new islands mean you go to a zone, but can walk to other areas easy ... so I was wondering if there was anyway I can set the tracker to only show the quests in the zone I am in.. what would be perfect is a drop down menu by zone like in the map window.. so yuou can press a plus button to hide to collapse tracked quests by zone while you are working on a area.

Anything like that?

PS - I mean normal quests, not world quests.
