You can juggle multiple tabs in Chrome, and you can juggle multiple windows. With Chrome extension Picture in Picture Viewer, you gain a third option: the ability to open a Web page as a Chrome panel. It's a great way to dock your Facebook news feed, Twitter feed, or a YouTube video, whether you are keeping an eye on a TED talk or a Cleveland Browns game from the mid-1980's when Bernie Kosar was at the height of his powers.

When the Picture in Picture Viewer extension installs, it places a button to the right of Chrome's URL bar. Clicking on the button opens your current page in a Chrome panel, but before you can do so, you have to enable Chrome's experimental Panels feature. Head to chrome://flags/#enable-panels and click Enable for the Enable Panels option and restart Chrome.
With panels enabled, the extension will open your current page with a click of its button. A small window drops down from the button as well, letting you enter a URL to open another panel. Click on the gear icon on this window to adjust two settings. You can enable Mobile View, which will open the mobile version of a site when available. And you can enable Embed View, which for YouTube, for example, opens only the video player for a video instead of the full YouTube page. Both settings are enabled by default, and it is my opinion the extension is most useful this way. I wish there was a third setting that closed your current tab when you opened it as a panel, but instead it stays open as a rule.
On the extension's page in the Chrome Web Store, it warns against right-clicking in a panel because it will crash Chrome. I tried it and can attest that Chrome does indeed crash with a single right-click in a panel. You've been warned, twice.
