I am always impressed by this plugin and the hard work / dedication that FireproofSocks has gone to continually develop and improve the ability of WordPress to handle Content Types like a good CMS should.
This plugin has allowed me to handle a good majority of the strange requests I get when developing websites and overall I am very pleased with everything.
I love that even after months of using this plugin it is continually being updated and changed to fix bugs and add features. I am always excited to see what new updates will be brought into the next release when I install this plugin on a brand new website (I just noticed the add meta-box feature today and it looks great)
I would recommend this Custom Content Type plugin to anyone who needs advanced / additional control over posts and pages on their website.
