Comment 5 for bug 733233

Mark, I'd ask you to reconsider as a lot of designs from the design team are dependant on the border-less approach, and I think that trend will continue (having large dark areas at the top of the window titlebar + toolbar/tabs) and then normal coloured "content" areas at the bottom.

The UbuntuOne control centre, Chromium and the imageview really benefit from this as the content is allowed to pop out more. I've attached some examples of what I mean.
