Hi, for a few days i was wondering if it would be possible to implement a system of "pinned messages" at the top in chatrooms, such as telegram, so that a message you want to make known gets noticed by every user in the room. i know there's a similar command (/announcement), but pinning messages at the top would be useful in case you always want to bring attention to something in particular (for example in the Italian room there are open registrations for a tournament, and it would be nice to pin the message with the registration link - at the top of the chatroom, so that it's always immediately available to everyone), with the opportunity to hide it by the user, in case he no longer wants to see it
