My memory failed me. Also thanks for the explanation. I guess if we could run in the past we would change how ! commands got added.

Purely from a command design perspective. Maybe it would have been optimal that these commands could just be /blue, /red, /green, /yellow, /k, and /swap, without the use of any boolean arguments. But that's from a design standpoint.

How would you feel if the / and ! would be interchangable? But the ! commands are kept as a legacy option? Just in case of a potentional autocomplete command feature.
