Enable hyperlinked indexes
A number of large 'Real Book' type files come complete with hyperlinked indexes. For instance 'Beatles Complete' and 'The Great Gig Book'. The idea is that you can tap any song name in the index of the book, and you jump to that song in the book. This works perfectly in othet music readers like ForScore - but not in Unrealbook. It makes Unrealbook almost useless in gig situations, where you need to quickly locate a song in a 'fakebook'.
Hyperlinked indexes require you to go to that page over and over. The indexes in unrealBook allow you to search and use the real books like any other file.
