I have an idea:

Listen my dear friends in Christ, being a missionary I have used many Bible apps, and this one tops all. I happily paid for the NIV version but it has other versions and language translations for free as well. Excellent app! You get MORE than you pay for!
Heres my idea: history. Like on my browser, if a close a page I can look to see where I was. I was reading 1 Kings yesterday, but today I cant remember where I left off and I didnt bookmark it. So in the window where users select chapter and verse, have the last read verse for easy return!
