Great app!
This was exactly what I was looking for. I have a home music studio with one 27in monitor for my DAW and sometimes I just need that extra screen for a project and I dont want a permanent screen so this works perfectly every time on Windows 8.1 and iPad. The only recommendation I would make to the developers is to reduce the amount of RAM on the desktop side it uses even more so that it takes away as little as possible from the work being done on the computer. Keep working on this app and it will be flawless!
