ModPE Library
this library helps you to use material design and minecraft UI(include minecraft font). Also, it includes a lot of ModPE functions and Math, Array, String, Vector, Entity Objects.
(example)
var btn = new pe.seize.widget.Button().setText("Button").setParams(75 * Utils.DP, 45 * Utils.DP).get(); //create a material design button.
