To only display the options for one panel at a time, Control -click (Mac) | Right -click (Win) on any panel header and select Solo Mode. While in Solo Mode, clicking on a panel header expands the contents of that panel while collapsing any other open panels (which can be especially useful when working on a laptop or smaller display as it eliminates the need to scroll through several open panels to access options).
You can also Option -click (Mac) | Alt -click (Win) the disclosure triangle on the panel header to quickly toggle Solo Mode. Note: the disclosure triangle icon is solid gray when Solo Mode is disabled and changes to dots when enabled).
To display more than one panel while still in Solo Mode, Shift -click an additional panel’s header.
