I would love to have this feature — especially when I want to have an UPDATE or CORRECTION comment highly visible. And there are other cases where a member's comment adds a TON of value to guide the conversation.

LinkedIn had a pinned comment feature, but removed it — and users have been FURIOUS because it's common on other platforms. It should be common in communities too.

This is really critical for me/us. I lose a lot of time scrolling up in thread history trying to find old messages, when I just want to be able to save/pin/star it like in Slack or Facebook or LinkedIn... most other platforms offer some form of this functionality
