Auto-downloading of threads?

Because of the nature of 4chan I constantly have to download threads and use DownThemAll to get the images. This is fucking tedious because

1 I have to keep coming back to save the page
2 DownThemAll still needs to be manually guided to start downloading much further than from the FIRST IMAGE because that's just wasting time


I'd like to be able to just one click a thread and have the script keep downloading that thread until it dies, but intelligently. So it would download new updates alone, and not download the entire page each time. It would also download the newest images, and not bother starting to download from the top.


Any greasemonkey scripts for this?
