Hello, I would switch to Iron (or even back to Chrome) right away if only this feature was enabled. Incognito mode IS NOT an option, is not the same, it doesn't work the same. I, for example, want the session to be completely open and fully automatic until I close the browser, then delete everything but the cookies. I want to remember open sessions and have websites suggest me based only on what I see around. I don't save any password.
Comodo Dragon has this option beautifully integrated but they never update to the latest version and it takes weeks before they release patches to annoying problems.
