What does the collapse icon do in the browser panel?

The collapse icon in the browser panel is primarily designed to hide or show the browser itself. This allows users to maximize their workspace by removing the browser panel from view when it is not needed and easily restore it when required. This functionality is particularly useful for providing a cleaner, less cluttered interface, enabling users to focus on their work without distractions.

Options that suggest showing hidden features, minimizing specific lists, or rearranging document order do not accurately describe the core function of the collapse icon. Instead, its main purpose is to toggle the visibility of the entire browser panel, offering flexibility in managing the display of the user interface.
