I’ve just downloaded Volumio2 and I’m loving it! It mostly works just as I want it to work and it turns out my old RPi 1B can be put to a sensible use again, yay!
Anyway, what I find irritating in the UI: the desktop and mobile sites have the buttons in opposite locations. The playback buttons are at top on desktop site, and at bottom on mobile site. Since the sites just switch instantly when one resizes the window, I often see either of them on the same device. This leads to a inconsistent experience, I start moving the mouse up, only to discover that my buttons are at the bottom this time.
I propose to unify the interface and keep the mobile set up: function switcher at top, playback buttons at bottom. It seems more natural that way.
