Are you trying to gaslight/troll us now? Separate user accounts is precisely the mechanism of having your own configuration on a multiuser system. Log out of Hacker News right now (or open in a private window or whatever), and then tell us how to "easily" configure showdead/noprocrast/topcolor etc without an account. How do I sit down at my Mac or BSD or Linux machine and have everything the way I want with no logging in?
Seriously, what the fuck are you talking about?
