Just like the /pin command it would be great if streamers and mods could use /unpin in chat to unpin the current active pinned message.

I often check my stream and chat on mobile when im AFK and quite often I notice I have a pinned message I want to unpin. Unpinning just by sending /unpin to chat would be awesome.

I personally also prefer keyboard > mouse so I would definitely use /unpin even at desktop. :3
