You can essentially make a playlist, I do it all the time for music videos
on the file click the options button
Go down to "Add to queue"
Do this for all your files
Then from the home screen, press the blue button, this will bring up the bottom option bar, where you can select favorites and such.
Selected "Queue" and this is essentially the playlist, it's not perfect but it works
I have not found a way to randomize what plays
