    • Systems and methods for displaying tab elements representing viewable page elements. A set of one or more main tabs are displayed on a first portion of a display, each main tab defining a link to a database object stored in a database. A user selection of a first one of the main tabs is received (e.g., to determine which tab provides default display), and two or more side tabs are displayed in a first, default order on a second portion of the display, each said side tab defining a link to an element or portion of a first object. In certain aspects, a user selection of a new order for the two or more side tabs is received, and thereafter the two or more side tabs are displayed in the new order, and the new order is stored to the database, wherein upon later access of the first object by the user, the two or more side tabs are automatically displayed in the new order.
