Hello guys! First of all, I am loving this so I would like to leave my humble suggestion.
I am not sure about how the timing for each lesson is determined, but I have noticed that I spend the whole day with some reviews here and there, and then all of a sudden BOOM - I will have 42+ lessons and/or 42+ reviews lined up that will take forever to complete.
Is this part of the learning process to go through a bunch at once? If so, once you start one of those massive reviews, is there a way to stop in the middle of it and continue afterwards?
Thank you and keep up with the good work!!
