If i click on the favorite icon (heart) on the home screen to add the current track to my favorite list, the icon change to full colour. so far all good 
But when the next track comes up the icon still remains clicked status and you believe this track is on your list too, but is not. Even if i refresh the whole homescreen by clicking on volumio logo the favorite icon gets no update.
Solution: every time the icon is clicked it have to get an update of its status showing if the track is on list or not
Am i the first person who recognize an missing status update for the favorite icon???
