Convert Akafuku to work on 4chan?

Hello /prog/

Let me start this out by saying that I know nothing about programming.

I am a Futaba (www.2chan.net) user, and over there we have a wonderful set of Firefox extensions known as Akafuku and Aima Aima ni (http://www.unmht.org/futaba/).  These do far more than the 4chan Firefox Extension, and include such features as one-click image saving, thread archiving, pop-up windows that display the target of >>(postnumber), or even >(quote) on mouseover, extensive spam filters, etc. etc.

Having a program like this for 4chan would be fucking awesome.  I know 4chan is based off of Futaba, but how hard would it be to reverse engineer this to work with 4chan?

Thread archiving, batch saving and searching has already been covered well enough by chanmongler. It works perfectly with all browsers (that is ie, opera and failurefox). There is simply no reason to write another tool to do the exact same stuff.
