A short, very informative tutorial on how to add an options page to your custom theme. I just had the need to include a functions.php file for the first time, so this tutorial, and the included template for the options page is exactly what I was looking for in taking theme design to the next level. Undersigned has provided several great tutorials lately, including this post on SEO and WordPress. In his *spare* time, he’s also updating the ever popular theme viewer. Just another example why the WP community is one of the best.
