When I use the file picker dialogue and hover over the mounts, I see some nice bars which show the quota of the mounts. How can I have the same functionality in dolphin?

settings -> configure Dolphin -> general -> status bar -> show space information
it will show on bottom right

Yeah, I know this, but IMHO this is ugly and it also moves the slider away from the lower right...

I meant the very same functionality. show it in the mount menu on mouse hover.
