1. better gesture support (swipe up, swipe down, two finger tap, three finger tap etc.... could all be used for customizable functions). For example, I find that returning to the previous book is very awkward. After looking up a word, a simple two finger swipe should be able to take you back to the Bible text.
2. in the library, a simple/separate list of books that are available offline
3. the word "look up" gives the text, MSS, Lemma, Morpy and Strong's number... but does not link to any Strong's dictionary. I would like access to Vine or the Strong's dictionary. (Strangely, the "Bible Word Study" does not use the Strong's number or link to Vine.
4. most of the charts that I have seen on the iPad are basically useless. The formatting is way off.
