I'm a new to the Fancy Product Designer (and to Wordpress development in general) so forgive me if my questions are ignorant.  I am attempting to customize some functionality of FPD and have not found a great way to do it other than modifying the plugin code itself.  Does FPD provide hooks to allow easy customization?  If not any thoughts on how to proceed with customization would be appreciated.  Thanks! 

Sorry, no it does not allow customization with hooks, you'd have to edit the code, this could help: http://jquerydoc.fancyproductdesigner.com/.
