Stef,
I think it would be a great thing if there is an option in CPT to make the frame change colour automatically if a position is assigned to be a tabiya position. This would help photographic memory remember better crucial positions.
Let me know if you have already incorporated this idea to CPT anytime soon because it would really help me more in my opening training.
Thank you if you consider.
Cheers.
