Konsole in KDE 4 allows setting up a number of useful shell title variants (using building blocks like the current program name, the current directory, etc.) in its profiles, which Konsole and Yakuake show in their title bars and/or tab labels. Konversation could use the channel/query topic widget in Konsole views to display the shell title, which KPart emits via its setWindowCaption(const QString&) signal.
