New TOC

So now that the page count of the thesis book is done, I redid the table of contents with new info and tried to clean up the design a bit. How do people like it? Clear? Good layout? Enough detail? I've been staring at it for so long I've lost perspective but I think color coding the bubbles to reflect the three main sections is a good idea. Comments?

Thanks

A variation...more to come I suspect.

The final cover

Just as a point of interest, here's the final. Publisher and authors were all happy.
