Shuntu, you do need to click the upper right hand "shop name" then when the page changes, click the left hand "sections" to make changes to those.
I like the new format....maybe play around with it a bit and wait through the weekend before you make any changes going back to the old view.
I like that it shows our items along the top of the page and down towards the right hand side bottom. It at least keeps customers on our page longer.
Good Luck with your etsy.
