I don't remember exactly how I got to it, but I opened a page (external possibly) that only showed the chat interface of facebook. It was quite similar to the gabtastik screenshot
What I wanted was, to create a Chrome Application shortcut for this page, and easily use Facebook chat as a side along application. However, I've not been able to find such a page. Is it possible to open the facebook chat only interface directly (without using any third party scripts)?
Once logged into facebook you could use the url
This no longer works (as of 12th October 2011)
or from any facebook page chat (in the bottom left) -> options -> pop out
The second option no longer works with the new Chat UI - 18th July 2011
