G15 Possibilities
 

Hmm, I know this cannot currently be done, but perhaps with the ability to send game info to an LCD screen on a keyboard, perhaps the same type of code can be used to allow game info (and perhaps game windows) outside of the game screen (IE have the game on one monitor and some windows on another monitor). I doubt this will work this way, or even be possible with the G15 additions, but the idea is definitely in the right place with the G15 mods....just think of it, having the ability to put some or all of your interface windows on a second screen to be able to enjoy the game without all the clutter of the Interface (without hiding the interface entirely)

Well....

There is a G15 emulator that you could put on another screen, but you are limited to the size of the G15 screen.

I use two monitors...I admit that it would sometimes be nice to be able to move the Broker Window or the Guild Window to the other screen.

But, to be completly honest, whilst you were out adventuring, you need your group window/hotbars/chat window so that you can immediatly see what is going on. Most other windows can be hidden when not needed.
