I.R. Brainiac: Is there anything in particular that you are worried the new SKS will not let you do?
Hard to tell from screenshots...but it looks like the sections you are working on are not shown in place in relationship to the rest of the skin...currently SKS center window attempts to show the elements in place(as opposed to sitting on a plain white background like in the screenshotts)
Till we get a chance to use it we really cant say,but it looks styled after Vistas personalize dialog and me personally I hated what MS did to the usability and configurability of Vista.(tree navigation in the start menu...aaaaaarrgh!)
I'm sure there is lots we are not seeing so I'm not too worried yet...
