Anu suggestion? :-)

Uh, Menu Bar like the Add to Panel dialog says? Adding Calum.

Hmm.  That would probably suffice, although it's not very descriptive and might
look a bit like it's referring to the whole panel, which does look a bit like a
"menu bar".  More likely you'd want to use the applet description that's used in
the "Add to Panel" dialog-- currently that just appears to be "A custom menu
bar", which isn't very helpful either, but I'm sure we can fix that :)

Ideally, though, you'd really want a tooltip for each individual menu title as
you moused over it, with a short description of what's on that menu.  I'm
guessing that's not currently possible...?

It might be possible. I'll try to take a look at it when we branch.

Patch

Calum: it's possible with a small workaround. The tooltips immediately appear,
though (small bug).

Now, if someone can come with good strings, that would be really helpful ;-)

Hmm, how about something like:

Applications: Browse and run installed applications by category.
Places: Open and search local, remote and recently-used documents and folders.
Desktop: Change desktop appearance and behaviour, get online help, or log out.

Improvements welcome :)

revised patch

Incorporated Calums suggestions and modified them a bit

Applications menu
Browse and run installed applications

Places menu
Browse, access and search local and remote data

Desktop menu
System administration, preferences and help

wondering why the tooltip delay is not working. I can set the delay to 5 as well with no visible difference. I can set it in the three panel_menu_bar_enter_* functions - no difference.

Fixed in HEAD. After looking at the GTK+ code, the fact that there's no delay is normal (it's a sticky tooltip).
