  Alternatively, you can just double-click any tab to hide the top toolbar or display it again.

• Status Bar – when this option is disabled, the bottommost bar where the Zoom, Fit to page, Fit to width buttons are situated will be hidden. To show the hidden Status Bar, enable this option.

When the Comments or Chat panel is opened, the width of the left sidebar is adjusted by simple drag-and-drop: move the mouse cursor over the left sidebar border so that it turns into the bidirectional arrow and drag the border to the right to extend the width of the sidebar. To restore its original width, move the border to the left.
