Please unbold/grey/change color of headlines that have been opened and read.
Please differentiate between headlines that have been clicked on, and read, as opposed to those that aren't clicked on.
It seems the green tag (unread) disappears after the headline is loaded, but headlines should only be marked "read" after being clicked on.

Hope for a quick solution here. This feature would bring TheOldReader right up to Google Reader's standard. There's currently no way to distinguish between read/unread items without selecting the feed again.

Maybe try:
http://userstyles.org/styles/87850/the-old-reader-unbold-unread-postsbut I think this might have been solved by The Old Reader by adding "do not mark loaded items as read" setting. Someone should clean up this uservoice ;)
