"Read" feature for posts on dev.to

Hi DEV team,
You people have done a fabulous job in keeping the dev community together. Kudos !

Being a blog reader, I'll always have dev.to website open even at my workplace. The only difficulty is to keep track of what posts I've already read. This becomes even worse when the network refreshes.

So, my request is about whether a feature like "post read" can be added on 'posts scrolled above x%'. Also, I'm not able to figure out how the posts are ordered. [They seem random sometimes, not chronological].

Thank you.

Happy coding everyone.
