I run a local site listing the articles in blog feature , and I want registred users to be able to filter read and unread articles inside that specific section or sections, or category, etc...

After user logs in, and going to that part of site articles titles would have something like a "NEW" icon near it that would vanish after user opens that same article.

So Joomla would know which articles have been or have not been read by each registred user. Besides icon I would like a selection filter,so that user could list all, unread or read articles.

On backpanel I could see which users read a specific article or which articles have a specific user read.

Is it possible with K2?

someone know any component for this functionality?

Thanks
