Earlier, a Chrome extension called Inbox Theme for Gmail was also released which claims to offer similar features to Inbox by Gmail.
Now, a new Chrome extension has been released by the co-creator of Inbox by Gmail that brings a similar experience to Gmail on the Web. While Google is busy bringing some of the Inbox by Gmail features to the regular Gmail app, there are a few Chrome browser Web extensions that can bring a similar, cleaner interface to your Gmail inbox. Inbox by Gmail was shut down earlier this week, and since then everyone has been on the lookout for an alternative.
