1. A non-transitory computer-readable medium having stored thereon computer-readable instructions that, when executed by a computer, cause the computer to perform operations for adding a user-selectable element to a destination array or user-selectable elements on a display, the operations comprising: adding a user-selectable element from a group of departure user-selectable elements, adapted to be grouped on the display along a first axis to provide a visual continuity between adjacent user-selectable elements thereof on a basis of a substantially rectilinear arrangement of user-selectable elements, to a destination array of user-selectable elements, the destination array of user-selectable elements being adapted to group a plurality of user-selectable elements having a commonality, the group of destination user-selectable elements being adapted to be grouped on the display along a second axis to provide a visual continuity between adjacent user-selectable elements thereof on a basis of a substantially rectilinear arrangement of user-selectable elements, the group of departure user-selectable elements and the group of destination user-selectable elements being adapted to be acted upon independently, the added user-selectable element being adapted to acquire the commonality by being added to the destination array of user-selectable elements, wherein the acquired commonality is adapted to be removed from the added user-selectable element when the added user-selectable element is removed from the group of destination user-selectable elements.
