How to build an chrome extension like Google Hangouts

Question

The Google Hangouts extension has a panel that shows up outside of the Chrome UI.

It is sort of like a notification but not. I don\'t see anything in the Extension D

Answer 1

It is an options of chrome.windows.create. Make sure you set type to panel.

chrome.windows.create({ url: 'https://mobile.twitter.com/', type: 'panel' });

panel may not be supported on all platforms and you may have to specifically enable panels in Chrome Flags chrome://flags/#enable-panels.
