Go to "Options > Configure Gestures" to see what each gesture does. E.g., speed up to 1.5x or slow down to a few frames per second, pause, play, zoom, etc. You can also customize or turn off the gestures.
Sometimes, you want to see a scene frame-by-frame or zoom-in to a specific spot in the frame; this video player allows you to do that.
Also, it is a stable player. I have not encounter any crashes or hangs.
One suggestion, items in a locked folder should not automatically show up in the "Recently Played" playlist category because doing so defeats the purpose of having a locked/secured folder.
