Should Exposé have application icons?

[mainstreetmark]

So, now that I rely on Exposé, I've found several situation where I have to do a bit of hunting for the window I'm after. After all, Dreamweaver source views look very similar to BB Edit windows, especially when enough windows are open and everything is small.

An optional application icon would help me identify the windows quicker, similar to how WindowShadeX's minimize-in-place feature works.
