Really Useful

If you’re using multiple Google accounts, this is an excellent tool. it allows me to keep two accounts open at any one time - I manage at least 20 accounts for the web sites I develop and support. But even if you don’t have that many, this tool saves the mindless Google opening and closing needed when working with multiple Gmails at the same time.
