It would be really helpful to have 汉子 only versions of the PDFs, or even a 汉子 only page attached to the current PDFs. This would make it easier to improve character recognition.
It’s often difficult to refrain from reading the pinyin/English instead of reading the characters. I know the premium version offers this facility in the ‘dialogue’ box but it would still be better to have a downloadable/printable version… even if it was a premium feature.
I understand that would be time consuming to retrospectively apply, but if it could be considered for future lessons that would be greatly appreciated.
