All Mail Button for Inbox by Gmail

Gmail has a great option to view 'All Mail', which includes labeled, archived, and otherwise sorted mail.
Inbox by Gmail is a fantastic new webapp, but sadly lacks the `All Mail` option.

Not to worry, though! This tiny extension comes to the rescue, adding a button to Inbox's sidebar, right under "Reminders".

Its aesthetic design is in line with the rest of Inbox's design language, and it keeps the experience streamlined.

When clicked, it inputs the "in:all" query into the search box and emulates a search event so that all of the mail appears, just like in Gmail.

The source code itself is under 50 lines, has no dependencies, and runs super fast. You're welcome to view it at:
