I liked the pinned tabs feature in Chrome, because it allows me to keep certain pages, such as Pandora and a Jira dashboard, open all the time, without taking up much space. The only problem is I often navigate away from these pages unintentionally.
This extension keeps a pinned tab pinned to a page.
To install the extension, go to chrome://extensions, check the "developer mode" box, select "Load unpacked extension...", and point to this directory. That's it!
