//Previously, you first required appjs, then called appjs.init(), which returns an app object. We can merge that into just one step.
var app = require('appjs');


//This is the basic way to call a window. You pass either a string with the URL of the window content, or you pass a full object, if you want to set more options.
var main_window = app.createWindow({

 * 
 * Character count with whitespace trimmed: 178.

#Social Network Crawler User Agents Users can post URLs on a lot of different platforms nowadays. Most of those platforms will send a request to that URL to generate some preview data from it.

These are a couple of user agents I quickly tested out.
