What's the best way to add new features?

Hi all,
I've downloaded this wonderful shopping cart as a replacement for a commercial cart that I've been using for many years. I love that it is very clean and FAST!

I'm interested in extending the functionality mainly on the admin's end.
I was wondering if there's a preferred method for "upgrading" the administration panel and functionality.

Now I'm guessing that programming modules will be the best way instead of modifying the default code of the cart. If so, are there any simple tutorials on how to go about creating a module that extends the back end? I just need a starting point. eg. something as simple as when the module is enabled, a new button appears on the products page (backend).

Thanks.

there really is no idea of a module that extends the backend. The best you can do is make your stuff in new pages and use vqmod to add it to the menu's
