Mark as unread when a post is edited?

[LosOjos]

Was just thinking, it's quite easy to miss edited posts, might it be a good idea to mark threads as unread if an earlier post is edited, or show that an edit has been made in some way?

Hmm I dont think it would be easy to do, I may reduce the edit time frame further which would mitigate the issue.
