Pi MusicBox with touchscreen control?

Hi, is there a way to have a PI MusicBox gui on a touchscreen?

I have a Raspberry PI 3 and a Raspberry PI 3 7" touchscreen display

Yes this is possible. My way: install ioBroker including web-adapter and VIS environment.
Then install Firefox-ESR (Version is important!) and start it in an X-session.

In ioBroker you should create a page with VIS. On this page you can integrate any mopidy web-client in an iframe widget.
From there you can control it with the touchscreen.

It’s also possible to directly control mopidy via the MPD adapter here.

Can you share the commands which where nessery for having a GUI?
