I haven't tried it, but it may be what you are looking for.
If you use one pc and one screen just use a maximizer and you can swich pritty easy, keyclone has a nice pip feature i use it for questing all the time.

along with focus'ed macros you can even swich your "main" pritty easy. great for those gather quests you want the rewards from...

/spits out awful taste of gather quest
