AWL Builder

I downloaded this app for improving my knowledge of English vocab. The concept of the app is really grateful and helpful. Thank you for developing this. However, I notice that a bug is in this app. When I was checking words for flash card, I scrolled the words list and the checkbox I chose were deleted. I wanna you fix this bug, please. And I want you to make a bottun for chioosing all words for flash card. It's annoying to push many bottuns many times..... And also I want examples of words in this app to understand how to use those. If you can accept my offer, it would be great help to people like me to understand English more. Thank you.
