Can quest helper be a tab in a chat window?

[Toccata]

I'm not sure if this is possible, but...

I'd love to have exactly two text windows on the bottom of my screen. One would be my "Main Chat", and the other would be "Secondary Chat/Quest Helper".

If I'm in combat (i.e. group XP, raid, etc) then I'd like the second window to show combat info (standard chat tabs showing my hits, others hits, etc). But if I'm working on a quest, I'd like the second window to be the quest helper. I never really need to see both at the same time.

Is there any way to embed the quest helper as a tab on a chat window like this?

Thanks!
