I'm sure I'm not the only person using a dual-monitor setup, and I very specifically DON'T want to set the monitor I use for gaming at the "primary" display, because if I'm multi-tasking, I want new windows or tasks to open on the monitor I'm NOT using to play a game.

In my case, my left monitor is my "primary" display, and my right monitor is what I use to play games on.

It's certainly not some major pressing issue or anything, but would be nice. My PC kinda struggles to run FFXIV to begin with, and running the game in windowed mode is unfortunately just a bit more taxing, so being able to run as fullscreen but choose my display would be a godsend!
