Users can fix the width or height of a window in order to protect the window from unwanted resizing. This constraint on the window width or height can be removed by the appropriate release operation. The layout can be saved and retrieved any time later to allow users to switch back and forth among different work layouts easily.
Users can undo or redo operations at any time.
This makes the window operations reversible. Not all operations are undo-able e.g. close operation. Multiple window operations can also be achieved by serial application of a window operation to a number of windows. Once the users selects the operation, it can be applied to any window by clicking on the window. This operation is particularly useful when removing a number of windows from a group.
