Folders4Gmail works again after it broke because of an improvement to Gmail. This seems to happen every half a year or so…
Get the updated version from the Folders4Gmail page.
Many thanks to everyone who volunteered to test the update! You made my life a lot easier. 
My bachelor thesis:
Abstract
The program Crocopat was created – among other things – to find design patterns. But it has its own input format and cannot read Java source code directly. So it is hard to determine how good the program really is in finding design patterns.
The goal of this paper is to create a tool, which converts Java projects into Crocopat’s input format. Then different design patterns shall be tested to evaluate how well searching for design patterns with Crocopat really works.
A week after Gmail added Drag and Drop to their labels, Folders4Gmail is working again. Get the latest version here.
Also, remember that you should select show all in Gmail’s Settings > Labels tab.
This is not strictly necessary for Folders4Gmail to work. But if you don’t select show all, half of your labels will hide in the sublabels and the other half under Gmail’sá More button.
Sorry to all of you who have waited patiently for the update. Unfortunately, this time fixing the script was much harder than usual.
Update:
The update (version 1.5) didn’t work with ths Gmail Labs Tasks feature. Fixed in version 1.51. Thanks to Scott Dafforn, who found the problem.
Update 2 (July 9, 2009) The updated script (version 1.5) used a lot of CPU time. Hopefully, the problem should be fixed now (version 1.52).
Update: Since October 2009 you should use Google Docs Batch Export instead.
Since last month the Google Docs Data API has support for downloading documents. Here’s a small demo that downloads 10 of your documents as a .zip file.
Limits
The demo will only download up to 10 documents and it won’t download documents bigger than 1 MB. This is because the demo runs on Google App Engine, which restricts the size and response time of HTTP-responses.
Try it out
Gmail made some very minor changes to their website (they renamed their Html-classes). Unfortunately, it was enough to break Folders4Gmail.
Please install the latest version of Folders4Gmail to make it work again.
Version 1.41 also works better with right-to-left languages like Hebrew and Arabic.
For those of you using Better Gmail 2, I emailed lifehacker.com about the update. So there should be an update for Better Gmail in a couple of days.
Sorry for the trouble. Unfortunately, userscripts are very vulnerable to such small website changes.
[Update March 5th, 2009]
The update for Better Gmail is available now
Folders4Gmail got an update to version 1.4.
New:
