Unread topics should be different colours or bolded

It would be nice if topics I've posted in could have a star next to them, or be bolded. Unread topics that I haven't seen could be a different colours. And then read topics with no new activity stay how they are now lol

 

Unread threads are in bold, and threads in which you have posted have your avatar inset in relation to the avatar of the OP. For example:

 

Ohh. Interesting. I've never even bothered to look at the avatars. Thanks.
