Hi WP hackers!
I come here just for opine about some funcionality that makes the WordPress a very robust CMS (you all know about it), and it is the post meta datas. It makes the WordPress a very tool for any type of content management systems, but the usage of the meta data is only hard coded. I have used a plugin called More Fields (maybe you already have knew about) that makes the usage of the meta keys very easy.
Why not make it a standard feature for the future WordPress versions?
Here is my tip. :)
