Definitely promising, but needs some bugs fixed

I love the look, the layout, and the text emoji choices. The random capitalization issue appears to be fixed. Remaining issues:

1. It needs to offer options to change words by selecting a previously typed word.

2. It needs to switch back to the alpha keyboard after using punctuation from one of the symbol keyboards.

3. It needs to do a better job of prediction, taking into account previous user choices, especially when the user goes back and fixes an incorrectly interpreted sequence.
