You can't sort iron chests anymore like you could in 1.6.4

Since cpw isn't developing mods anymore, not something I'm likely to look at any time soon.

Well iron chests is a mod that's out for 1.7.2, I'm not sure if it's the same developer but it's the same page as the old versions and it's annoying not to be able to sort the chests

progwml6 has taken over ironchest

i can get you any info if needed
