As I once mentioned on another thread, we are making a song book app containing multiple books with alternate version(s) of songs and we use \cp markers to assign alternative chapter numbers to those songs (e.g. 24A, 24B, etc.). Here’s the link to our app on Google Play Store: https://play.google.com/store/apps/details?id=org.sabda.kidung. As of SAB version 5.3, this works really well on the app bar and on the song index as well. However, recently we found that whenever we perform searches in the app, the search results would still return the value of \c marker instead of \cp as book chapter references for those found items.
This might lead some users to think that there is an error in the numbering of the songs. Please look into the issue. Thanks.
