I know Ultramon had this feature, but when I discovered Display Fusion I made myself a promise that I'd never ever turn back.
But there's one feature I really miss, and that the opportunity to start a game on a specific monitor. Like, right click the game shortcut, and "start on monitor 2" or something like that. I'm sure you know about the feature.
And on a side note, this feature is utterly broken in Ultramon if you're using an ATI 4870X2 card. I don't know why, but I think it's because of the way it handles the primary monitor. I know for a fact that it was a mess to even change the primary monitor in vista, but in w7 it seems to be fixed. And that's why I think a option like this is possible.
Reason I'm requesting this is because I often play games on my TV (which is connected to my computer, together with 2 other monitors), and as it is now, I have to manually change the primary monitor to play a game, which results in buggy wallpapers and a lot of mess.
Bottom line; you're doing an awesome job creating this program, and I think you've hijacked quite a lot of Ultramon users. I have at least made 5 of my friends change
Keep up the good work.

edit: I mentioned it, but to make it clear; yes I'm using the Windows 7 x64 7100 build.
