Maybe a option for radio to replace logo

hi guys,
we have low res images on the radio stations…
is there a way if you want a option to replace the low res image with a hi-res version of the radio station
it would give volumio a slicker feel to it…

and a ajustable width of the scrollbar would be a nice option to.
on my screen it’s not really useable with a 3mm of space to catch the bar.
