Unfortunately not. My PC is away in storage right now and it looks like the Gallery's been given a bit of a spring clean. It used to be in there.
Basically I swapped the large Bluecurve panel for two smaller ones. The first of these sits permanently at the bottom of the screen, taking up the full width, and houses the most used commands. For me this includes (from right to left) Show Desktop, Launch Firefox, Launch CLI, Switch Desktop (just 2 because this is all I ever need), Taskbar, Clock. Everything else, including the start menu, commonly used programs and system info goes in a narrower second panel that folds away when I don't need it.
I really like the customisability of the Gnome and KDE UIs actually. It's worth spending a bit of time experimenting with different layouts to improve ease-of-use in the long run. And I guess it makes sense cos everybody would probably use their system in a slightly different way given the choice. (One only has to read the CLI versus GUI debates to see that!)
I too prefer the Bluecurve theme to the icy look of the OS X theme. Initially I was really taken by it but actually Bluecurve and metacity are really kind on the eyes whereas OS X gets a bit tiring. And yeah, anything's an improvement on Windows XP.
Btw, the Bluecurve XMMS skin is also available for Winamp for those who care. Heh, if only Bluecurve were available for Windows.
