chrisak: The last version of Personal Menu backs up and restores your data with the rest of the settings. I thought I had put this in a much earlier version, but there was a problem with it. The next version of Personal Launcher will have this too.

Good point about the browser URL. When you add it from "Select from installed applications" it uses the DBUS line to execute instead of the executable. Adding url= doesn't do anything. Adding manually is definitely the way to go.
