There is a very irritating problem that occurs on almost every (but not all) insertion of an external USB drive: the indicator box pops up top right on the screen but generally cannot be made to disappear. Clicking on it or the icon has no effect (this is if I don’t want to mount the volume eg if only charging a device). If I click it to mount the volume a file browser window (nautilus ?) opens and occasionally the popped out indicator disappears - but usually not. This is super-irritating as it covers the new tab area in a maximised Firefox. As I type now the box has gone leaving behind an up arrow floating.
It would be nice if this indicator had an x on it like the printing etc messages - and hid itself automatically after a couple of seconds.
