This feels like table stakes. There currently is no way at all to view any information or have any indication of the dates associated with the replies.

IE: If I have 20 posts in a channel, each with their own set of replies, the only way I can find out which post has a new reply is to either

A) Follow and receive notifications for every post

B) Manually click them one at a time to find the date on the latest reply.

People need to be able to see at a glance the most recently updated posts without having to follow every post in every channel.
