Every day I work I wish for a single feature in Visual Studio: the ability to move a code file from Visual Studio to another monitor. I can't stand the fact that I can't do this! Even if I switch to MDI view Visual Studio only lets each window move around within Visual Studio and not to other monitors. I would love to have a few code files dispersed on various monitors so that I can see more of what I'm doing at any given time.
In this day and age is this too much to ask? Why the constraint?
I'm sure I can come up with others (I can imagine that Rjae, in particular, has numerous wishes), but this one tops my current list now that I'm using more than one monitor. And, for those that aren't, you really should be. Fork over some cash and join the club. Spending the money is a no brainer in relation to the increased output you get with multiple monitors. It's an investment worth making.
