Great idea, but buggy app

I used to love the app for its many functions. However, even after deleting the app, re-installing and restoring bookmarks as instructed on their website, it still is a buggy app. For instance, the highlighting feature either gives and error message or crashes. This is very frustrating, particularly when in church and trying to focus on the message. Again, while I love the concept and have purchased multiple translations for use on this app, it is unreliable.
