Multi-Monitor Metro Apps - Windows Blue
I did not see this anywhere, nor any pic's but Windows Blue supports multi-monitor metro apps. This is a lot better than the way Windows 8 handles which cannot run more than one monitor with a metro app at a time.
EDIT: some extra notes,
- The apps themselves are no longer restricted to the small 320px size that they use to have. Instead they can be from 320px to any size greater
- The second change is that when you go into the Welcome Screen on multi-monitors it no longer shuffles the apps to that selected monitor. Instead the app will retain its position no matter which screen you start the desktop on. Also the start screen button is now instant instead of fading in, and is always on the bottom left corner of either monitor.
