Good App with missing iTunes features

This app is one of the rare iTunes control apps on the market. It also controls Winamp, which I didnt test.
Overall, it does what it says: It controls iTunes (and Winamp). But for me, iTunes is closely coupled with AirPlay, and this app does not support switching the Airplay speaker. I tried to contact the support but I got just "marketing answers", but very friendly.
The volume control should be a slider, because it is hard to control (even to see the volume while pressing the minus or plus button. It is quite easy to accidently manipulate the playlists (delete songs etc.) in iTunes - be careful!
If the airplay functionality is not needed, this app is very good. For me, it is useless, because I have to stand up from my couch to change the airplay speaker on my PC.

PS
I have to start the app as administrator on my Win7 PC to work.
