I'd like to suggest adding a feature to automatically @ tag/mention the person you are replying to. I've seen sometimes users (especially those new to Community) forget to @ the person they are replying to, assuming by clicking reply the other person will get a Notification, but that's not the case. I think this feature will make a difference so people don't have to turn on "Email me when someone replies" or subscribe to the post to get notified of every single reply.
