@thomasfuchs A a browser feature to indicate that you have an account/particular cookie/etc., and then style things on other sites based on it (without indicating to the other site) would be really cool.

For example, sticking an open lock icon next to links to Washington Post, which I have an account for, but a lock icon next to links to The Atlantic, which I don't — but across all sites, as a browser feature.

(this would probably never work but it would be cool)
