In the new navigation you find your modules in a red menu on the left.The modules are shown as icons. You can see when the icons represent by hovering your mouse on them. Or click on the "hamburger" 
at the top of the side menu to expand it and quickly scan down the list of modules.
Understanding where you are
At the top of the page, you can see the name of the workspace in black and underneath the name of the current module. A white indicator in the side menu also points to the current module.
All about you
Clicking on your image, or initials if you haven't yet uploaded an image, will show you the settings and shortcuts that are just for you. Here you can, for instance, change setting for your account (email address, password), add a picture of yourself, change language in the interface, or change between workspaces available to you. This is also where you can, for a period of time, change between the new navigation and classic Webforum.
