I have picked up some great feedback about the application and will implement the functionality in the near future. The end user wanted know if I could include a “space bar” in the app. Sure! It was suggested that the app be allowed to rotate to landscape mode… Since the app is just for the iPhone and screen size is at a premium, I don’t envision that happening. However, it won’t hurt to look at that kind of implementation. I could cascade the characters by splitting the screen and placing the pieces next to each other. Or, allow for scrolling in landscape mode, or lastly try the scroll-wheel for each character set. The last sounds intriguing to me. All three are possible, so the question becomes one of application and usability.
