Learning to chant the Sutras

Allowing the user to repeat any Sutra as many times as it takes is essential to learning it.
This app is wonderful. The chanting is beautiful, and is perfectly formatted if one merely wants to listen to the Sutras. But one who wants to learn to chant the Sutras cant advance or replay individual Sutras without advancing or replaying the entire chapter. Please look into modifying this. It would take this app from wonderful to above and beyond.
Many thanks.

Should be asleep about Patanjali's Yoga Sutra, v1.1.4
