Marked with a new reply

This is a suggestion I've read on invz. It'd be great to have it :)

Is there anyway that this can be done?

So that if the last post in the topic is edited at some point, it will go thru and mark the topic as being unread and having a new post.

That way people who have already read the post will have some indication that it has had something added.

Please and thank you.
