Strongs Underline Option in KJV Bible (iPad)

In the King James Version (1769) with Strongs Numbers and Morphology, it would be very helpful and easier to have an option to indicate words with a Strong's reference as "Underlined" instead of numbered. As you can imagine it is less distractive than the numbering. It is something that I became accustomed to using the Mantis Study Bible on the iPhone/iPad. This is just a suggestion for an enhancement. eSword for the iPhone and iPad is a blessing for me, please continue this project and I can't say Thank You enough.
