[q] [rom feature request for nook hd, hd+] topic

Hey, I was wondering if anyone had the time and effort to add a mod to CyanogenMod, like CM11 or CM12? Because what would be really cool would be a multi-window feature baked into the ROM, like what Samsung has done. That would be an amazing feature if anyone had the precious time to do it, or just make a flashable zip to add the feature...:D Thanks for anyone's consideration!
