Your keyboard does take up much more space. As well as reducing what else you can see in the app you are working i find it difficult to span the height with my thumbs. Could you create a setting allowing people to select height they found best?
Resize keyboard for better use of screen
Since I use this keyboard I tought about the size and now, with the beta I realized that some changes can be made.
First with the prediction bar, it grows the keyboard a lot, before it was bigger than iOs keyboard and now it's more.
Without this bar it's a great size considering the multiple features offered that iOs keyboard doesn't have.
It's just an option, a mockup of how you can use less screen and offer more WRIO keyboard. :D
- The left screenshot have just a reduced size for the buttons of 80% comparing it with 100% of the originals. And they stills been bigger than iOs buttons.
- Some space is empty so, I tougth about using the recent emojis from the emoji section, and put in there the first 6.
I don't know if you tought before about the size of the buttons but, I think it may be a good idea making them a little bit smaller, may be not too much, but you know better than anyone how this great keyboard works.
