Great App, but recent update removed feature – Prompt 2 Review

I love this app, but a recent update removed the "hide keyboard" button from my iPhone 5S. I saw it still exists on the larger phones (6/6s) but it's very difficult to see the screen output without being able to hide the keyboard. Please bring this feature back for iPhone 5s/5se users!
