A software application assists users of a computing device to manipulate a data object displayed on a user interface. The software application may be implemented as a method that may comprise receiving a touch-and-hold operation directed to the data object, and responsive to the touch-and-hold operation, determining whether a time period since beginning of the touch-and-hold operation reaches a predetermined threshold value, when the time period reaches the predetermined threshold value, creating an image of the data object and hovering the image of the data object on top of the data object to indicate it is draggable, and responsive to the image of the data object being dragged into a droppable display area on the user interface, swapping the image of the data object with a user guidance indicating what the image of the data object will look like if released in the droppable display area. |
