Hello Ashley and Kosta,
I have the visible keys turned on, and I noticed I am more comfortable with the keys visible, even though I really can't see them as opposed to just the white lines on the custom keyboard. Weird, huh!
As I said in an earlier email I was playing with the reduced height option and I think if two more lines were visible to be able to interact with all an emails fields, and a gesture to insert text in a field may be another solution for a half screen option.
PS all seems to be working fine.
