I posted this in the general Chess Mentor Forum, but wanted to post it here as well.

Are there any plans to be able to flag/bookmark specific lessons in the future.  Such as "Lesson completely mastered no need to see again,"  "Particulatly instructive lesson I want to come back to,"  "Interesting lesson that I would like to be able to find in the future."  etc.  There could be flags of different colors representing these different aspects of our lessons and we could set a training session for certain flagged courses.

great idea!

It is a good idea. Is it in place yet?

No, I don't think there are any definite plans for this feature yet.  But I hope that the staff would consider doing this as it could be very helpful for training.
