Bible search on the fly has always been slow. The current (and long-standing) system of drop down menus can often be difficult to find and display Bible verses quickly. The preacher or prayer leader has moved on by the time the display is up. It should be possible to create buttons (Genesis through Revelation) and then have buttons for chapters, then select first verse with the rest following.
I've seen it done by OliveTree for mobile phone, ie you click, for instance, Genesis, then Chapter 3, then Verse 5 which instantly displays with all following verses waiting to scroll after.
I'd love to see something of the sort, if only as an option, as I guess the current system suits some.
