For my setup I have a Tablet set as a second monitor, so when I play DS or 3DS games I have a touch screen. It's really nice, I have one of those "Stretch conrollers" so the tablet sits in the middle like a Wii U. Anyways, I want my Big Box setup, and honestly lauchbox too if possible, to use my second monitor as a Marquee when single monitor consoles are being played, but when I play a console that uses the second monitor, obviously use it as a second monitor instead of the marquee. Is there anyway to do this, or any plugins that may help me out? I'm pretty new to all of this, but the end goal is to build a fancy cabinet for my kids.
