Feature Request: Bookmark articles and if possible then in multiple lists

I am learning and brushing up my JS skills by this site only, I am learning from beginning to the end.

While reading I realized that there are some articles which I need to revisit regularly so that they are fresh in my mind, some are there which I would like to read later and some are very fabulous articles to which I would refer always when I need to understand or to explain someone the same.

So for this, I propose a feature to bookmark articles, also, if possible then in multiple lists like below:

• Favorite
• Read Later
• Important

Though only a single "Bookmark" feature will also help a lot.

We can discuss the need for such a feature here and once we are OK to have the feature we can discuss how to implement it.
