I just got the latest SVN, and was playing around with it, and the title change feature is in there, which is great, but there seems to be something wrong with it. The title is now "Dialer - Dialer - (page)", while it should be "Dialer - (page)" The solution I found was to get rid of "Dialer - " in any calls to self._window.set_title (there were two I found, and it's actually "%s - " and self.__pretty_app_name__). Everything seems to be working great now. Good work on everything!
