1. A computer-implemented method comprising: receiving selection, through a single continuous gesture from a user, of a selected tile of multiple tiles displayed in a first view in a user interface, the selection moving the selected tile from a current location among the multiple tiles to a designated region of the user interface including receiving a first dragging portion of the single continuous gesture that drags the selected tile to the designated region, the designated region being one of a top edge of the user interface, a bottom edge of the user interface, or a marked area within the user interface separated from the multiple tiles, said marked area configured to display tiles at a smaller size than the size at which the multiple tiles are displayed; responsive solely to the selection moving the selected tile to the designated region and without receiving another gesture from the user, zooming out from the first view to a second view during reception of the single continuous gesture, the second view including at least a portion of the multiple tiles displayed in the first view and multiple other tiles not displayed in the first view; receiving another selection through the single continuous gesture, the other selection moving the selected tile to a new location in the second view, the other selection including receiving a second dragging portion of the single continuous gesture that drags the selected tile from the designated region to the new location; zooming into the new location during reception of the single continuous gesture, the zooming in presenting a third view, the third view including the new location and one or more of the multiple other tiles, the new location occupied by a current tile of the multiple other tiles; indicating that the new location is valid by altering an appearance of a tile above the new location or the current tile; placing the selected tile at the new location; and automatically reflowing one or more of the multiple other tiles.
