When you’ve got lots of post meta-boxes, your post edit screen can become difficult to search. Make your post edit screen easier to navigate and manage by creating a set of tabs, with the Tabify Edit Screen plugin. And manage it all from the WordPress back-end!
There are still lots of things changing in the code base. There are some hooks you can use but they can change from implementation till 1.0. I will always try to maintain backwards-compatible but till 1.0 I can’t be sure for that.
