Multi-Monitor UI

Vouch! Im upgrading to dual monitor with my wife's income tax... BOOM!!

I can see where it'd be nice. Personally don't use two monitors, mostly because I'm in college and without a job, but also no space on my desk.

It would be a sweet feature that I'd love to have somewhere down the line for sure but let's face the reality here: Dual monitor setup is far less common than single monitor and even if it was not it's just gravy, there are so many things that are much more important to spend time on.
