After upgrade to 12.04, the Unity toolbar has the custom launchers I had added to gnome panels under 10.04. When I go to gnome classic however, the panels aren't there, and there are no launchers.

I would like to resurrect them in gnome classic, or at least see the code I put in the command line of the launchers.

Where is that information stored? Is there a way to see launcher properties in Unity? Under gnome, you can edit the launcher's command. If I could do the same under Unity, I could at least see how I configured those launchers and then redo them.
