Renamed.

NEW:

- Double-click in a popup *pins* it. Won't close even if the parent popup is not pinned.
- Alt + Double-click *opens the popup as a tab* and closes it.
- Clicking on any popup window *highlights all related popup windows*.
- Middle-clicking anywhere except on a link inside a popup will *close* it, even if pinned (especially if pinned, otherwise closing it is as easy as clicking anywhere inside the main browser window).

NOTE:

- If you use the middle click to activate the scroll functionality, I highly recommend you install the *ScrollAnywhere* extension and set it to use clicking and holding the left mouse button to scroll instead. Much more intuitive, almost like using an expensive Logitech MX Master 3 Scroll Wheel.
- If you use the *Zen* browser, *deactivate* the option "Open links in tabs instead of new windows", since the extension is handling default window opening behavior.
