RPI3 How to exit FullScreen Music playback on Tochscreen?

Hi dear community,

I love the Titan-Skin on my Raspberry Pi3 with 7″ Touchscreen. The only issue I experience is:

When in music playback I switch to fullsreen to have all the great fanart I normally can exit fullscreen by tapping on the screen. But sometimes exit fullscreen does not work, then I have to restart my pi or press “home” on my iPhone remote app. I guess I am not able to exit fullscreen mode only when Titan does not find any fanart and gets stuck on searching. Could that be a reason? When fanart slideshow is shown in fullscreen I can tap on the display and exit fullscreen. Also the start-stop-pause….. buttons do not show up, when titan cannot find fanart in fullscreen mode.

Is it possible to have a “home” or “exit” button in a corner that shows up at touch? Or any other help?

Great skin!
best regards
Karsten
