Facebook Old Chat Sidebar for Greasemonkey

Script Summary: Replaces new Facebook chat sidebar with one like the original - 2013

Version: 2.3.0

Script homepage

Works with Firefox 21, Google Chrome 27 & Opera 12 (tested)

This userscript replaces the new Facebook Chat Sidebar with one like the original!
It hooks Facebooks internal functions to display the old chat.
By the way the new Feed ticker is integrated in the right bar and isn't depending on the chat anymore.
It really works, even with the Timeline update ;) Please share this userscript or write a review!

General Information:

Overview: https://www.facebook.com/bookmarks/lists

When you're adding friends to lists or create a new one refresh the page after you're done.

Create friend lists: Click on "Create List" in the overview.

Hide/Show friend lists permanently: navigate to the overview.
Select a list, click "Manage Lists" in the upper right corner and choose "Archive List" (can be restored).
This works for all lists besides from "Close Friends", "Acquaintances" and "Restricted".
You can empty these lists to hide them.

Order of lists: In general they will be shown in order of their creation date, but you can easily reorder them!

Persistence: This userscript uses localStorage to store settings.
When you clear cookies, the localStorage will be cleared as well.
