One of the terms you’ll hear a lot within the WordPress community is Metaboxes. These boxes are what users interact with the most when using WordPress. For instance, when writing a post, you interact with the Publish, Categories, Tags and if need be, Post Format metaboxes. If you are a developer or consultant, the chances are pretty high that you’ll be creating one or more of these for your projects. If you don’t fancy writing all of the code to create those metaboxes, check out Bill Ericksons Custom Meta Boxes plugin.
