Gmail Sunshine is a Chrome extension developed by Petr Sloup that brings back the beloved feature from Google Inbox to Gmail. With the discontinuation of Google Inbox, many users have had to switch back to using Gmail. However, one essential feature was missing - the satisfying feeling of seeing a sunny icon when you have cleared all your incoming emails.

Gmail Sunshine solves this issue by adding a sunshine icon to your Gmail interface when there are no new emails in your inbox. This simple yet delightful feature provides users with a visual confirmation that they have successfully gone through all their emails and have no more work to do.

With its easy installation process and seamless integration into Gmail, Gmail Sunshine is a must-have extension for those who miss the sunny days of Google Inbox.
