In order to optimize the area of the application, it is possible to use the functionality of window docking which allows for displaying two or more windows next to each other. To do so, it is necessary to open selected windows and drag the tab of a given window to the center of the main window.  A place in which the dragged window can be arranged is indicated with the arrows. To place the new window in a given place, it is necessary to trop its tab over the proper part of the symbol. Other windows can be placed in any place of the active window.
