Polaris is one of our most popular “workhorse” designs — it uses a basic left-hand text navigation menu and three columns of thumbnails.
This design supports Sets. If you use Sets to organize your Project List, the navigation of this design can reflect this organization on the front-end. You can change how to use Sets in your Display Options > Using Sets.
Polaris also uses an expanded version of our Slideshow module that contains a variety of extra options. You can find these in your Display Options > Slideshow Options.
