The page goes along as it is, sign-ins, scroll position and typed text included, and every window comes back after a restart. Sidebar panels have a bar on top with Maximize/Restore and Close, and open either over the page (a click in the page closes them) or beside it, pushing the page aside: pick in the new gear on the sidebar or in Settings › Sidebar. This replaces the pin. Also fixes a window that came back blank after being minimized.</div>
