Your comment should be on top. Everything OP said can easily be done with Chrome's multiple profile feature. I love the fact that I can run _multiple_ incognito sessions at the same time without it being bounded by the number of browsers you have. Multiple Gmail sessions? No problem. You can just setup a profile for each email account you own without requiring you to sign-in every time.
