The curse of being a developer is that I understand everything I do, and just about everything everyone else does because I read their code... So, when I write an extension - It makes perfect sense to me.
Several of my extensions have the capability for very advanced/complicated configurations. Top of the Page is one of them.
I plan on writing some in-depth how-to articles about my extensions in the future.
Email me and I'll be happy to give a step-by-step to achieve your goal.
