Help Simple questions on VLC for Android

[pentel]

Love this VLC player for playing videos, works great and no ads.

Tried using VLC as a music/audio player and have some simple questions per this screenshot:

1. What does the "two arrow" button, marked in the red box on the bottom left do?

2. What does the "two arrow" button, marked in the red box on the bottom right do?

3. Where is the "stop" button if I want to stop playing the mp3 file on this screen?

two arrows that cross each other: looks like shuffle.
two arrows in a loop: well, it's loop. Either playlist or song. Probably works with multiple taps.
to stop, just press pause and back out of the app. It will remember where you stopped. Simply start a new song if you want to start over.
