As you scroll your news feed in expanded view, it now automatically marks the articles on the screen as read. Now you need not have to mark individual article as read when you scroll down your feed.

It also marks an article as read when you click on the title or expand the node to read full article text. And also if you are using keyboard shortcut j/k or n/p to browse the next article in a feed. 

Please let us know if this works perfectly for you. Incase there are any issue please let us know at team{at}feedspot{dot com}
