Re: Straightforward solution
When I exit my browser it zaps cookies. I can't ask it to remember things (eg logins) when I then tell it to forget things.
People (lazy sods that they are) want the computer to do the work for them. Most don't care about cookies, don't care about their web activity being tracked, and see the popups asking "will you accept cookies" as an annoyance.
What you, and a lot of the others on this forum seem to want is "remember things that make it easier for me and forget the rest" but the problem comes from the fact that the computer has to remember what to forget - woops.
