The Pattern Launcher Rocks

I guess you do:

if (Bangle["#ontouch"]!==undefined) 
  Bangle.on("touch", e => {
    Bangle.showLauncher();
  });

That's where touch handlers are defined, so calling that allows you to check to see if anything is currently using touch?

... And wrt the gestures - the code is already in there, I just haven't done a launcher using it yet. But even when I do I feel like there's something very clean about dragging in the 3x3 grid so it may be something people prefer anyway
