For those who upgrade from an earlier version:
The feature "Jukebox Feature" has been split into the two features "Developer's Jukebox" and "Developer's Jukebox third party". The latter will change very rarely.
On http://www.eclipse-plugins.info, somebody commented: "When you can dnd songs then it might be useful". There you are. It was easier then expected, thanks to EMF.
You can use the eclipse update manager to update to the latest release of Developer's Jukebox.
