Collapse Conversations

When looking at the communication within a pulse in the conversation, there are many that we have going on. It would be very helpful to be able collapse them, possibly to even create titles for them so users can put their notes in various threads within the conversation and then for a conversation that has been dealt with to be archived when no longer needed, but so we can pull it up if need be (or greyed out…or some option so we know it’s good) instead of deleted.
Thank you
