Please consider a setting to enable markup on chat comment for move numbers. Clicking on the move link will take the goban to that position in the game.
For example, a chat comment like “Wow, move 34 was great” and clicking on move 34 will navigate you to that point in the game. Similar to the Shift+click behaviour on the goban.
I hope I explained it properly. Possible implementations could ask the user to markup the link correctly (“Wow, /m34 was great”) or to have the code parse all chats and markup “move 34” without the user doing anything.
