The tab feature is something we use a lot. We use it majorly for Bible discussion questions. So, it appears on every chapter such that a user can access the questions programmed for that book. The caveat however, is that we have to add it for each book, there seems to be no way to add it directly at Book Collections level. This becomes time consuming if I have about 5-7 Book Collections, and I have to add the Discussion questions tab at the book level for each collection.
I’m wondering if this can be added to subsequent updates?
