Interfaces utilize two types of tiles, including boundary spanning type tiles and boundary non-spanning type tiles. The boundary non-spanning tile each have a boundary non-spanning parameter/property that prevent the tile from overlapping a particular type of display boundary and that is operable for triggering a modification of a layout presentation of the canvas by causing/modifying the one or more tiles in the first set of tiles to be automatically resized and/or repositioned within the canvas layout presentation when it is determined the boundary non-spanning type tile(s) would overlap the particular type of boundary in a current/prior layout. The boundary spanning type tiles omit the boundary non-spanning parameter/property or have it set to an inactive state.
