FastCompany profiles a new Chrome plugin in this article published today: https://www.fastcompany.com/90338929/the-former-lead-designer-of-gmail-just-fixed-gmail-on-his-own . The plugin greatly simplifies Gmail’s interface – and it’s made by the same person who wrote Inbox.
I loved using Inbox, and I see the same design sensibilities from Inbox in this plugin: a focus on the email instead of wasting screen real estate on navigation bars and miscellany.
