LINKDING

This one is indispensable for GitHub browsing. Gives you a full tree view of any repo on the left side of the page so you can quickly navigate between files and explore repos where you wouldn't even know what to search for in the GitHub quick switcher.

Allows you to extract tabs based on a title search to a new window from the url bar. It's handier than it might sound, especially for use with any of the tab-set-saving extensions.

Add keyboard navigation (play/pause, fast forward, rewind) to any HTML5 video you run across.

And when you get to the point where you just have too many extensions, use Extension manager to quickly enable and disable them, and create sets of extensions for bulk enable/disable as circumstance requires.

OneTab is the de facto solution for saving tab sets. Click the extension button and the whole window is saved to an organized list where you can drag between sets and remove tabs as needed. **Tip:** export OneTab lists as plain text for easy bulk editing and import it again to clean up long lists.

This one scratches an itch for me. I use Toby and Pinboard to organize tabs, which is way easier if I can just save a whole window, but I hate having my sessions include irrelevant pages, and sorting them all is a pain. With Tab Manager, you can see all of your tabs as a list and manipulate them in myriad ways (close, move, re-order). See also OneTab...

A handy plugin (similar to my [TabLinks](http://brettterpstra.com/projects/tablinks/) extension for Safari) that copies all of your open tabs as a list of text links. Like TabLinks, it allows a template so you can, say, copy as a bullet list of Markdown URLs with page titles.

An interesting extension that uses an algorithm based on the times tabs are active to sort them by "relevance."

I've mentioned this one before, but it's amazingly handy if you have multiple Twitter accounts, giving you an easy dropdown for instantly switching between accounts on the Twitter website.

I usually use the tab switcher built into [Vimium](https://chrome.google.com/webstore/detail/vimium/dbepggeogbaibhgnhhndojpepiihcmeb), but this plugin allows quick switching, reordering, and closing Chrome tabs from a dropdown, which is handy.

Another way to get Hacker News, Designer News, and Product Hunt into your Chrome new tab page, plus GitHub, Pushbullet, and more.
