A lot of people seem to not realize that Dolphin can eject mounted volumes. You can, of course: Just right-click on it and choose Unmount '<disk>'. Many people don't seem to think of that. It would be nice if we added a little eject symbol next to mounted disks in the Places panel, so that people could visually see that ejecting is possible, and could furthermore do it with one click.
Yep, actions that are available only in context-menus are bad UX.
Here's an additional idea on the same subject that I ran across while screen Dolphin bugs yesterday: https://bugs.kde.org/show_bug.cgi?id=149118 The idea is that when you're using Dolphin to browse a mounted disk, the window would be badged with a horizontal bar saying "Eject" or "safely unmount" or something.
As long as the "Click Happy" don't unmount the current root or home... :) Personally I think it's better leaving it "hidden" in the context menu.
You wouldn't be able to unmount /, since it's running the OS. /home would likely object as well if you had open files on it (also only a minority of new Linux distro installs create a separate /home partition anyway). And if you were able to unmount /home, you could just click it again from the Places list to re-mount it.
Indeed - You are quite correct. I apologise for the extraneous noise - must engage brain before writing comment.
