Panel Properties

Panels can be pinned, autohidden, closed or maximized.  The left and bottom panels are set to autohidden initially.

You can selectively enable corresponding action buttons, and can choose to enable a button either on all dock panels, or only on a specific one.  For example, all dock panels could be closed, except the bottom one.

When a panel is closed, it is hidden from the user. There is no built-in UI to re-open the panel. Closed panels can be re-opened with a client API call.
