SideBar is a collapsible vertical stack of buttons. Each button has its own panel. This panel, located above the button stack, is displayed when the button is selected. The height of the button stack can be adjusted by dragging the stack size bar. Buttons that do not fit in the stack overflow onto the footer, and finally onto the menu if the footer is full. SideBar can be configured via the configuration dialog accessible from the menu.
