Window and Board Size
The size of еру window can be changed by dragging its borders or with the help of buttons of window expansion in the right top corner of the window.
To maximize a window or to restore its size, it is possible to click twice also on the line of heading.
The sizes of the board also vary. The board is located in the left part of the window, so it occupies all its height or all its width (which is more).
