Different groups of people read differing compilations of rehraas. We can:
Include popular versions with labels (Such as Rehat Maryada, Extended Banis, Extended Chaupai & Anand Sahib)
Include ability in desktop to create custom banis. Possibly extend to a "banis store" online where people can download popular compilations
Include a setting to set all banis according to a specific School of Thought. (Personally against this approach as there are more customizable options above without hindering efficiency).
