GUI Elements for the 2.1 RP

Hi Hi,

I am once again asking for your resource pack-related assistance. I want to change some of the new UI elements for 2.1, but after using a java decompiler (fernflower option) on the server resource pack,jar yielding an empty .zip file, I was left without any leads. I assume its possible to decompile/decompress the pack, but I have not found a way to do so yet.

If any of you know, I would be grateful for you to show me how to.

Thanks for your time,
//Rythew
