So I finally figured out how to view my PMs as conversations (sad given how long I've been on the site, I know) and the first thing I noticed that the "reply to all" button was gone from conversations with multiple people. As I GM, Co GM, or am otherwise involved with groups, I need the "reply to all" button. But I like having my PMs in conversations.
So, is there a way to get it back but leave them as conversations (setting up labels, maybe)? If not, may I make the humble suggestion to add this function to conversations?
