If you click the Blogger "B" logo on the left side of the NavBar...
You'll see a list of all of your blogs. Each blog has a orange button to write a post and a drop-down menu to access all the menus like Layout, Template, and Settings.
Alternatively, you can click Design on the NavBar and you'll go to a Dashboard for the blog you are currently working on (instead of a Dashboard for ALL of your blogs). There are easy links to all of the other menus along the left side of the Dashboard.
