You might be able to do something similar with the Status Bar (bottom of the window), but you can't currently change what is displayed in the Title Bar (top of the window), except for the option which chooses between displaying full paths and just the folder name.
Yes, your right Leo, you can do something with the status bar using the dlab options. Its not quite what i'm looking for, but it will suffice for the time being. I have sent a request to see if this feature can be implemented in future versions.
