This could go in the data probe or elsewhere in the interface.

In general it would also be nice if the title bar of the window (the frame) included the name of the currently open scene file, like the way a word processor shows the currently open document.

In this case the title bar could say something like: "SPL Knee Atlas.mrml -- Scene: tibial plateau"

Excellent idea

Implemented DataProbe display in r22149

Looked into using title bar instead with something like this:

mw = mainWindow()
mw.setWindowTitle('test')

But I think if we are updating the title bar it should be done only on scene load and save, which would require some more research and/or re-assigning the request to Julien since he knows how he set up the load and save dialogs and would know where to add this.
