Advanced Gnome Menu (or AGM) is a combination between a menu and a dock. Even though the word 'Gnome' is in it's name, it will soon also work with KDE and Xfce (or it could already work, I can't test this as I only have Gnome installed).
It supports themes, plugins (actually this is what's displayed in it: the usual gnome menu, bookmarks, favorite apps, etc), transparency, etc.
To install it, download the source files or .deb files from here. NOTE to Ubuntu Jaunty users: the deb files won't work but there's a fix: just download from the same location the file called update_from_svn.sh and launch it with sudo permissions.

You can also download some themes from here (extract the archive, then import the themes into AGM) or just customize the existing one to what you like.
