Yeah, I just downloaded 1.0.0, and it has mostly what I'm looking for, so while I'm very curious why one would put out such a full-featured and powerful media player that lacks as basic a feature as GUI skip back/forward, I'll drop it
What I'm wondering now is how to add buttons to the fullscreen navigator (the one that pops up when you move the mouse, not the one in "fullscreen mode" that doesn't disappear). I was able to add the buttons I wanted to the regular GUI, but not for fullscreen....
