Marking post as read?

is there a setting here or can it be implemented, that any post you click on will show ( subject text ) a different color.
at times when browsing the forum, i have a hard time to go back to topics that i was on a few pages ago etc.
right now the topics are in a blue color,perhaps they can change to a different color if you have visited it before…
is that possible here ,or is it not possible ? i think it would be a great feature here in the forums.
