peter Not for me. I honestly never really touch anything except the song list and the volume fader at a gig. Too busy playing the piano while the backing track is playing ๐ Only song volume would even be enough as far as I'm concerned.
@Vedeja's idea led me to another idea though. Maybe this would be helpful if you need to save space for other assignable buttons:
So what if instead of having "Increase Song Volume" and "Decrease Song Volume" actions, you would only have "Song Volume"? The button would have the same size as currently, and would display the current song volume. Then, if you tap (or tap and hold), a fader would pop up (just like when you tap "Settings"). Then you could adjust the volume with the fader, and when you release (maybe with a small delay), it pops back "into" the button, which now displays the new volume.
This would be like hitting 3 flies at once: 1. you keep the current space for the buttons, 2. we get our beloved instant volume value, 3. you wouldn't need to re-add the extra Volume +/- buttons.
Since we now have pop up menus everywhere, I think this shouldn't be difficult to implement and would be really cool ๐
