This is an extension for Gnome 3.38 which puts minimize and close buttons in the top panel.
Note: Binary files aren't shown on the web site. To see all files, please download the extension zipfile.
Since you're targeting a recent version of GNOME Shell and GJS, you can just use `Function.prototype.bind()` and drop `Lang`. We only really needed that with ancient JS :) eg. `someObj.connect('some-signal', this.someCallback.bind(this));`
