Been doing some more work on the UI today.
As can be seen below - a progressbar implemented.
The volume slider is ugly, thinking of removing it all together and override the "hardware volume buttons". But then, not all devices may have such buttons...
I'd rather have the volume slider be vertically aligned too, but there doesnt seem to be a stock vertical slider.. May have to roll my own... Which I'd rather not do but rather spend my time on implementing new features.
Artist and Album browse is just around the corner. Servify/J supports them - need to figure out a nice way to display them in the UI.
