Comment 44 for bug 38512

Alleluja! There is a plugin which does not require patches to rhythmbox itself! My bad I didn't get it...

You can get it from there:

If you prefer I changed it a bit to get the correct animation when hiding the window:

As a side note would be nice to have this plugin easily installable in Ubuntu, but personally I'm already satisfied.
