Could be, but never should be. The animation class was meant for small areas,
in order to catch a little more attention to a change that could otherwise go
unnoticed to the user.

Well, I still do work on things that I have fun working on. Sorry if that
doesn't always map to the most important todo list items.

In case you have not noticed I actually do work on these issues.
Some of them are long solved:
- The device name issue is already solved (since 4.0.0) but just needs your
involvement (first point on http://phonon.kde.org/cms/1036).
- Devices that don't work are not shown or shown disabled (depending on
whether they ever worked before).
- If you plug in a USB device it is added to the list and kept even if you
unplug it again (since a long time already).
- How do you suggest to hide the Backend tab even more? Dialog in a dialog?

Looking pretty is one thing. Catching attention to a potentially minimal UI
change is the more important problem I wanted to solve.
