I wish Apple would add the cursor slider feature to the native keyboard. Its fantastic!
One star off because when I disable the predictive text, the bar at the top of the keyboard does not dock. It just sticks around as a solid block of color obstructing a chunk of my screen.
There are also some glitches, but these are okay.
I dont know what goes into making a third party theme work, but why is it necessary to allow the devs access to what I type?
