I'm sorry if I'm ruffeling anyones feathers as the application is free but these are my facts.
I set up blogs all the time, Hundreds!
I am very surprised how much more effort the new interface takes than the old. I use the All In One SEO and have to scroll up and down all the time. I usually spend a lot of time in the Settings menu. I'm scrolling up and down continuously. In addition I use several adsense add ins and must scroll to the bottom to get to them also.
People are moving toward wide screen monitors in the landscape format not portrait mode. I have a 24 inch monitor and it does me no good at all with the new interface. It feels like it was a step backward.
I vote you either make the menus movable or go back to the old.
I find myself in a dilemma where the 6 series was more efficient but to install the older 6 will take more time as the two hosting companies I use have upgraded to ver 7.
Rarely does a newer interface take more effort to operate but this one does.
