Follow along with the video below to see how to install our site as a web app on your home screen.
Note: This feature may not be available in some browsers.
Really this is more a function of the home screens, rather than the app drawer. You can dedicate different screens for different app types, or folders on the home screen. Plenty of space for apps and widgets.
There are alternative launchers I've used that allow for heavy custimization of the app drawer but personally I don't see too great a benefit of this.
