The item information handler obtains item information relating to items of a worksheet. The overview element handler manages overview elements based on the item information. Each overview element represents item information of a corresponding item of the worksheet. The overview area handler provides an overview area for containing the overview elements to make the overview elements contained in the overview area accessible by a user. The overview synchronizer synchronizes between each overview element in the overview area and its corresponding item of the worksheet.
