This is a Rhythmbox plugin that enables you to queue music to your play queue in a single click.
Simply middle click on your track and it goes in the list!
I will be updating this plugin in the coming weeks with GTK3 support.
Debian testing has pretty much completed the gnome3.0 migration with 3.2 not far behind. This will let me get onto supporting Rhythmbox git releases that distro's have been using.
