yes. claude added a suggested random scramble (if that's what you mean?), also running average of 5/12/100, local storage of past times on first iteration, my son told it to also add a button for +2s penalties and touch screen support.

Let me know if you adapt it in any way, my son would be delighted to see open source work its magic :)
