Raspberry Pi Musicbox with Display?!

Hello everybody,
I bought a PI 2 type B and want this converted into a Internet radio. Installs the whole already and I get through the speakers also records audio. So far everything well. Now I would like to install, however, a touch screen on the radio. Is it provided for in the jukebox an integrated surface? When I connect a display via HDMI I get only a text interface. Do I need an addon?

Musicbox has a webinterface by default. An option can be to display the web on the screen (I have never tried to do it).

But if you are interested in using a touchscreen I developed an extension: mopidy-touchscreen.
You have some more info in this thread.
