Chrome extension for using multiple Gmail accounts

I have multiple Gmail accounts that I use throughout the day and I developed a bad habit of keeping them open and constantly clicking through tabs to check the status of my inbox even though I know nothing’s changed. Checker Plus is a chrome extension that lets you preview, delete, star and archive email without opening up Gmail or leaving your current window, and it works with multiple accounts. Since I’ve been using it, I have definitely been more productive. — CD
