The bundle includes v2.3.5 of the YUI! Compressor which weighs in at about 900k, making an already large bundle a little larger. I've bound the command to ⌃⌘C to keep it consistent with the other compression commands.
If you've not already heard about the YUI! Compressor more information is available at the YUI! Developer site[1]. It's a lot like Dean Edwards' Packer but without the eval() and a different variable renaming scheme (which seems to improve gzip efficiency).
(The bundle is nearly 2mb compressed so I've made it available for download[2] instead of attaching it directly to the list)
