I really like this app. Just found it yesterday. Wanted to turn off my screen with a swipe or app(now I do with a swipe). It works perfect. This should be BUILT IN to SETTINGS\Advanced\Motions and gestures! However, it is readily available on Play and Galaxy stores, sooo, NP.
Have hidden the bottom native nav buttons. They still work, but are hard to reach one handed. Don't have to reach down for back/recent/home anymore.
Can go directly to app drawer from another program. Very usefull. A plethora of actions.
