Help with keyboard for BangleJS2 - Multitap/T9 layout

Nevermind, got it. A keyboard needs to look something like this:

exports.input = function(options) {
  options = options||{};
  var text = options.text;
  if ("string"!=typeof text) text="";

  SOME FUNCTIONS AND VARIABLES

  return new Promise((resolve,reject) => {
    layout = new Layout( { LAYOUT }
      ,{back: ()=>{
        Bangle.setUI();
        g.clearRect(Bangle.appRect);
        resolve(text);
      }});
    g.clearRect(Bangle.appRect);
    layout.render();
  });
};

I'll wrap it up into an app next.
