I really appreciate details like adjusting sound and vibrate with really fine adjustment, which alternatives neglect.
Things I wish it had:
*hyphenation and colons, etc are added with a space making it difficult to add new hyphenated words.
*backspace has to be held down to delete wrong words. I realize this preference may vary but I've gotten used to a backspace resulting in immediate deletion of entire wrong word, not only by a long press.
*wish the top and bottom bars were smaller
*wish the top bar had more suggestions and or scrolled right
*when the accent and unusual characters menu is disabled I wish holding down a key double long still offered the accent and unusual characters which turn out to be really hard to access unless it's enabled. Alternatively one could long press the number option for additional key maps.
Overall a great feeling and functioning, intuitive, fun keyboard comparable to an apple product and that is a high complement.
