NExS allows you to create multiple secondary windows of the spreadsheet data area which can be navigated independently of each other. Each view is a transient window which means it is always positioned on top of the main NExS window. Each secondary window can be resizedbut not iconified.
Secondary windows do not include a menu bar. However, any menu or operation selected from the main menu on the primary window is applied to any secondary window which has the current or selected cell(s) in view.
