Add to favorites.

Gentlemen with endless karma. I would like to know.
1 - Does the Favorites button work?
2 - If it works, where can I read my favorite articles?
3 - If the service is supposed to be done not for one day, then I have a question, whether there are any ideas on how to organize a personal “Favorites” section. As a user, I can say that I personally can copy articles from the site no longer interesting, but there are some examples . I am interested in the discussion and the text itself, but I have a question, initially add it to my favorites, does it work? Can I hope that Habr will store the information as carefully here, and can I refer to the article in the future with an indication that it is in my favorites (!), Or this link. Why I started talking about the elect, for sure you have tracked which articles fall into your favorites, and what conclusions can be drawn from this, and I don’t teach you on this topic. But as a user, it would be trivial to have an idea how to later work with articles, quote, etc. ... It seems that bloggers have gathered here and surely it will be interesting for everyone like the project, because
external links never get in the way.

Plus: can I make folders for selected articles? A la Novoteka, may there be greetings to Mr. Ashmanov from here ...

thank.
