During the 2008 UI Summit, one of the things that I mentioned is that once people get a file manager in software, you lose them. They don't understand navigation and files and directories (right Sebastian Faubel?). The two most popular features in OpenOffice believe it or not are the email button which automatically attaches the current document to Evolution, and also the picture gallery. When you click on the picture gallery button, clipart and photos are displayed and they can drop and drag them right into OOo Writer.
Pepp and Mbarnes have hacked on a patch to integrate that feature into Evolution. The beauty of the patch is that it consumes no real estate for those that don't want to use it. We currently have an icon on the desktop that opens Nautilus with emoticons and city logos; once this patch is merged I'll be able to move all of those pictures directly into Evolution.
OpenOffice allows you to add your own Galleries, so in theory the two could be synced for consistency.
