So, for example, as some of you may know, I'm making a hat thread. Whenever I make a new hat, I post an update. If people don't post during the time it takes for me to make a new hat and post a update, it seems like I'm double, triple, and even quadruple posting, when really, I'm just giving updates, because when you edit the main post, it doesn't assign the post as "unread" for other users.
So, what I'm suggesting, is for when the main post gets edited, it goes back to the top of the list of threads. However, this can be easily abused. So, my other suggestion, which I think you will agree on, is the make the post Blue, like this:

So that way, for example, when I make another hat, people will know, and that way I don't have to be a double, triple, or quadruple poster.
Also, there can be a option once you're finished editing the main post, you can make the blue not appear, for example, if you misspelled something.
So, what do you think?
