It would be great if the label of the current tab could be added to the window title. In this way you can use global auto-type features from password managers like KeePassX.
Can you explain the use case a little more?
In the password manager the entries have a window title fields which are matched with the title of the current window when a global shortcut is triggered and the password (or other fields) is send to the current window. For example when i want to open my ssh key ring i type "ssh-add" and the window title in Konsole contains now "ssh-add" (I configured the tab title format like this: "%d : %n"). Then i can hit the shortcurt and the correct password is send. At the moment i would have to configure all entries with the same window title "Yakuake" and choose from them everytime a trigger global auto-type in Yakuake. Another example is a sudo password on a remote host.
