It'd be nice to be able to show positions or games in posts. For instance perhaps with the notation :
<fen>rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1</fen>
<game>gIaZWDywKqzW</game>
The reference in the game tag just being a lichess game ID. Even better if you could specify a move with something like gIaZWDywKqzW#13.
