Auto-notify users when replying to post
When replying to a post, we currently have to tag the user for them to get a notification. It seems like replies should trigger a notification automatically - even better, make it a setting we can turn on or off (although I can't imagine why someone would want it off).

A setting for this is here: https://docs.mattermost.com/help/settings/account-settings.html#reply-notifications.

So glad this is planned. It's very hard to remember to tag people when replying to a post, but it can be days before they notice it since they don't get the notification of the reply unless they're actually tagged in it. This happens to me frequently even though I use it daily, I still sometimes don't see replies right away.
