One of the tradeoffs of iFly providing a consistent user interface across multiple platforms (Windows, Windows CE, iOS, Android) is that they have to forego some of the OS-unique features because they're not common to all platforms. The iOS and Android OS keyboards, and copy-and-paste, are examples of that.
That's a design choice that minimizes the headache of having to maintain unique aspects of the code for each platform, and is probably necessary for a small company like AP to efffectively support those multiple platforms. In other words, I suspect that design choice is unlikely to change in the near future.
