You probably have been using gesture-based navigation on your Android for years without thinking about it. That little pill at the bottom of the screen is delightful to use and barely takes up any space. But when you switch to buttons, like I've done, you enable several key features that make Android better. For example, enabling buttons gives you the ability to better control when the keyboard is showing, it enables the fastest possible way to switch between apps, and even Circle to Search gets better.
