Here's a suggestion. Please get shot of the awful second vertical list. It is a complete and utter eyesore, and nothing is where you expect it. Put the menu back horizontally where it is expected. Fill in the big white blank space to the right of 'Summary' where it used to go. Previous layout may not have been brilliant but it was 110% better and more usable than this one. Earlier suggestion about a theme manager is very sensible - it would mean you could properly test themes and get some user feedback. Having this nonsense foisted on us with no choice is just irresponsible. One seriously unhappy user.
