Reduce the height of the key on iPhones
I really like your iPhone keyboard but suggest that you look to reduce the height to the top of the QWERTY row to be the same as the standard iPhone keyboard (or even a little smaller). Right now the main Keys are higher and it means your hey board takes a more vertical space than it needs to, affecting usability
Taken a bit further, it would be lovely to have a "slim keyboar" option to reduce the total height to match the standard keyboard.
In the next version we will be enabling the “short mode” option when in portrait orientation. (It’s already enabled in landscape mode.) This will allow the keyboard to be actually shorter than the stock one, especially when the shorter suggestions bar is taken into account.
