Hi Zexon83,
I can tell you that the app is already a Universal App and has been tested for basic functionality within the desktop environment. That being said, there is still UI development that needs to be done in order to tailor the app for larger screens. The Windows Phone version of the app also makes use of the Pivot feature, which allows swiping between Rooms to allow for simpler organization of sensors. The Pivot feature is not available within the desktop environment, so the UI needs to be tweaked here as well.
As far as additional functionality, such as specialized Live Tiles, Cortana integration, etc, this will depend greatly on the amount of usage that the app receives. If Securifi feels that the investment to the app is justified, then these features may be brought into the backlog.
