I have been thinking about screen real estate and considering a second monitor. Began thinking about how other programs handle this and the most basic answer was right in front of me. The Auto Hide setting on my Windows Task Bar!!!
I propose that Revit make the Project Browser and the Design Bar "Auto Hide".
The way I see it working is that the toolbars could be docked at the right and left of the screen and when the mouse goes off the screen to the left or right the browser or design bar will float out.
What say you?
