I didn't think of this, but it's a great idea, only, I don't know right now how
difficult it will be. I'll have a look.

I'm not very sure of this (so check it), but I think you can retrieve the
GtkCombo's list selection, which is done like this:

GList* selected = GTK_LIST(GTK_COMBO(combo)->list)->selection;
guint index = GPOINTER_TO_UINT(selected->data);

There were no very important changes from this date, the only thing, which is
committed today, is the username stuff we talked about yesterday.
