While the player itself is the continuation of the foobar2k philosohpy (works like clock & customizable) there are still some features extremely important for improved usability, which are missing, namely:

Simple headset controls - double click/hold of the button for next track would be great! Can have triple click for previous track as well.

Variable playback speed - a simple option to set the speed in percentage for those listening to audiobooks and such, 10% steps would be most adequate.

I hope these will get implemented in the near future and make foobar the best yet again, but on mobile this time.
