Assuming you're running Gnome, as I'm not sure there's a freedesktop standard for the Bookmark feature yet (and perhaps there should be).
In every Gnome nautilus window, save dialog, and file open dialog there's a standard set of folders you see on the side as quick links. Some are obvious, and we duplicate them (eg Desktop), others are automatic, like gvfs links to external hard disks. Users can also add their own. Would it be appropriate to display those self-added bookmarks in Wine? I'm worried there might be something I'm missing about the implementation that would make this difficult or a bad idea.
