Is it possible to disable the single-tap to switch between documents when there are multiple documents associated with a song. I mostly use only the built-in database fields for lyrics/chords/notes but occasional songs may have a pdf with notes for the keyboard player. Other users get confused when they for example miss a button in their layout and the app suddenly switches to a different document. I think it would be better to enforce the use of the multiple-documents button to choose between documents, or at least have an option to do so in layout preferences.
