If a task is displayed in a view that holds multiple task columns, then the task may be dragged from one column to another.,
The drag process will change the data attributes of the dragged task to reflect the attributes of the target column. For instance, in the Week view, if a task is dragged from one day to another day column, then the scheduled date of the task will be automatically updated to reflect the scheduled date of the target column.
The drag action is only enabled if the user holds down the drag button for an extended time period.
The drag process is started and visible when the task entry appearance changes to show just the task title inside a black-rimmed rectangle.
