Another great toggle on the settings would be to have the application to go fullscreen on mobiles.
I think this is a great idea. I am thinking of a full-screen or "kiosk" mode that enables Wiim users to turn a tablet with the app installed into a live "album art" display. The UI would put album art first (and make it big, taking up half of the screen), be viewable in landscape mode (with art and son metadata side by side instead of stacked) and make the text readable from a reasonable distance away.
An example/go-by is the "Now Playing" plugin screen on my RPi4 w/ 7" touchscreen, running Volumio. See attached photo. Credit to the plugin developer. This feature would kill Volumio once and for all for me.
