So there is currently a copy URL to share a conversation with members of the team, but it would be really cool if we had the same options to share a conversation publicly. Its very common for us to say "If you reference our email on Nov 23rd" (or whatever) to remind client of an approval or message, but it would be super cool if we could actually link them directly to that conversation. I don't know of any email service that has done this, but imagine referencing past email to the recipient is a pretty common email pattern. Bonus Points for a Show / Hide Comments option in the public view.
