I've expanded the player statistics to include counts of the number of times a player has reached each of the target levels: Good, Better, Best, Maven, Cham. This arises from a suggestion by Morbius.
In case you're unaware of these statistics, you can bring them up once you're signed in to Chihuahua by clicking on the "Details" button near your player name and then clicking on the "Player statistics" button at the top right of the player details panel.
I've also implemented the change mentioned in the 7 by many club thread, to show the highest level each player has reached in a current puzzle when the mouse pointer on a computer hovers over the player's name, without clicking the mouse button.
I realise this doesn't fully satisfy Les's wishes, and he's perhaps the only person wanting some such recognition on the scoreboard, but it's as far as I'm willing to go.
