Do you use Google’s Inbox web client on your PC and get a lot of email? I do and I found a very useful Chrome extension today, which allows me to see an email notification count of unread email via the Favicon.
The Favicon is the tiny graphic to the left of the tab name, or the little icon you see on your favorites bar.
The advantage of this extension is that I don’t even have to have Inbox open to be able to see that I have unread email. 🙂
