Dynamic Views or "DynViews" control the display settings on the primary list pages. These pages would be the main pages a user lands on after clicking on tabs like "Projects", "Users", "Companies". These views can be accessed in the code of content pages to produce the resulting layout.
Each "view" has an id and a name. Add new views from this page. Click on the "View Name" entry to link to more detailed information about the specific details on the view.
From here, new columns can be added to the view, or existing ones can be modified by clicking on them, affecting the visual outcome.
