Often I find myself in the situation that I
- insert an USB drive
- open dolphin
- copy some files to or from it
- want to unmount it in order to make it ready to unplug

CURRENT STATE:

- The address bar shows something like "74,5 GiB Removable Media" (this means dolphin knows that it currently deals with a removable drive)
- The status bar contains these items on the right:
-- zoom slider
-- free space indicator

SUGGESTION:

- On the right-most corner - next to the free space indicator - there could be an item that makes it possible to unmount the drive (and automatically close the dolphin window?)
-- Rationale of why it could make sense to place the unmount next to the free space indicator: e.g. I load files to a stick and watch the indicator for free disk space. When it is (nearly) full the next action would be unmount.
- Additional benefit: if there are more than one removable devices attached, there will be no doubt or confusion about which is the correct drive to unmount. :)
