Howdy friends!
I was recently experimenting with WordPress page templates and realized that it might be quite difficult for beginners to understand what they are and how they work, which is why I suggest a more user friendly approach at displaying the page template picker in the edit page screen. The full post with a visual mockup could be found here: http://kovshenin.com/archives/a-thought-on-wordpress-page-templates/
I'd love to hear your thoughts, comments and suggestions. I can come up with an implementation patch too if necessary.
Cheers,
