Please add keystroke sounds

Hey, I have been enjoying the app more than any other I've ever used. I like the user interface, the stats, and the quality. But there is one thing that is in the other apps that makes me still abit attracted to other apps, and that is the 'Keystroke Sounds' feature. It gives a really good boost while typing. It will be so awesome if that feature could be implemented in this app as well. Then there will be no reason for me to switch to any other app, and I feel that'd be the case for most of us. But again, great app, I'm loving it. Lots of appreciation to you jdyn
