Finds them on its own
Install a Sidecar extension and it appears in the list by itself. Nothing to add, nothing to pair, no key to paste.
Sidecar / The panel
Eight extensions used to mean eight icons fighting over the same strip of toolbar. Now there is one. Click it and every Sidecar tool you have installed is listed, with a switch beside each, and a line telling you what it is doing on the page you are already looking at.

The panel is a light switch, not a control room. There is no settings page behind it.

02
Turning one off stops it in every tab already open. No reload, no restart.
03
Each row says what that tool is doing on the current page, or which site it waits for. A tool that is idle says so instead of pretending.
04
One switch pauses everything on the site in front of you and leaves the rest of the web alone. Useful for the one app that does not get along with anything.
The panel is optional. Every extension works without it.
