Reading and Managing new/unread posts

I wanted to make sure I logged these two critical items here and filed under the “bug” tag:

1. When reading posts in a board, there is no way to keep track of which posts have/have not been read, or which have new content that needs to be reviewed. In the previous forum software, new content was distinguishable with boldface in the topic titles. 
2. When viewing a list of posts in a board, there is no sorting mechanism to bring newer content to the top. If a user posts a reply to an older topic, that topic remains buried chronologically according to when the original topic was created. There is no sorting option to bring newer replies to the top for reading. 

There are a ton of other things, but these two in particular make it nearly impossible to read/manage/respond to posts in a reliable and effective way. 

Also, if any of the staff read this, it would be good to understand whether it’s better to break up a post like this one into two separate posts, one for each issue, or combine as I’ve done here.
