Searching the Bible is not very ideal on the iPhone app. Here is why I say this.
1. When you search for a word it gives a short list. You have to keep tapping to get more of the list. I would rather have the entire list show up with it nested by translations so that you have a list of translations, tap it and the list of results from that translation shown all in one page.
2. As someone else asked, how can i search one translation. I entered a search and it returned KJV results. This is not tied to the prioritized list since I have ESV prioritized in Logos 4.
