I'm not the big one to see faults in semantic, but let's see the syntax.
1. For the long list of CP, it would be nice to have an "allways to see" button to jump to the inicial view (on top?), instead of using the mouse to go up step by step
2. It seems you have used a fixed width for the columns. My screen has a high resolution, so I see a narrow column in the center. It would be more handsome if you use a relative width, so, idependent of the screen, you use the space available.
Overall, it's a usefull, with nice optical view, very complete, information. I think the users will like it.
