Active window title in Kubuntu panel?

view full story

http://askubuntu.com – I have Kubuntu 11.10 and have seen some people's desktops and they have the active window's title on their top panel like Unity and Macs do. I'm not looking for a global menu, they already have a widget for that preinstalled, I just want the title of the window (i.e. Google Chrome) to appear when it's open. I'm pretty sure it's a widget they have but I don't know what. Anyone know what I'm talking about? (HowTos)
