The EggRecentChooserWidget code is in CVS since a bunch of minutes, complete with a context menu allowing the removal of items from the list, the ability to add a custom RecentManager instance instead of using its own (still requires some polishing, but the interesting bits are there), and filtering based on a custom function. Also, I’ve fixed a nasty bug in the parser library that left garbage at the end of the storage file when removing items.
The next step is to allow the creation of RecentManager objects (maybe using runtime loadable modules) so that Gnome could use a GnomeVFS enabled resource monitoring in order to track location/file changes. This would require the implementation of RecentManager as a GInterface, as a plausible approach.
Anyway, now I’ll work on an applet/technology demonstrator, in order to have more to show to the Gtk people.
