I really like the design of this keyboard, but there are a few flaws that need to be fixed ASAP.
1. The backspace works intermittently. What usually happens is that while I try to backspace it keeps registering that Im typing more letters in so that gets nowhere. The swipe line shows up but it still keeps typing more letters in. Also, the hold and backspace button doesnt work. I would like to see a backspace button in the very bottom right corner below the space bar because swiping is too much of a hassle.
2. The enter swipe is very unreliable. Unlike the backspace swipe where you see a line indicating that you swiped, the enter swipe rarely shows a line and it rarely executes the command.
3. Emoji navigation is confusing. I am not sure how to access the entire emoji library from the keyboard.
This is a cool idea but the execution is poor.
