Okay, I'm working on a wish list of possible things to add. Here's my preliminary one based on revamping/remaking fancy 2 or introducing a similar but separate style, perhaps fancy 7! (I'm generating this list based off of an example from the "test" portion of my site: http://www.spinozarods.com/store/classic-reels/hardy-st-george-jr-trout-reel/)
(1) Paragraph styling in the description area - is this even possible? Right now it just lumps all product description text together but it would be great if you could use basic styling there: i.e., bolding things, new paragraphs, center-aligning text, etc. This is especially an issue if your product description is long!
(2) Multiple thumbnails - I love that we now have the option of including multiple photos for a product which you can cycle through in lightbox. However, it would also be good for the customer to know off the bat that there are multiple photos. My idea is to have one lead thumb but then include several smaller ones in a small row right underneath that lead.
(3) Having two effective columns in the product div -- so that way that the example above works there is a major area for product text but also a considerable column of space below the thumbnail area on the left. I'd love to be able to use that space to display things like variation, product quantity, "share via facebook twitter" links, links for reviews, perhaps short customer testimonials, etc... Basically all of the "extras" that don't really fit in the product description area but which would also be strange to have outside of the fancy display.
(4) Separate thumbnail link URL's for category pages and product pages -- when you include a link for the product thumb this works well on the category page where there are lots of products listed. Someone clicks on the picture and this takes them to the individual product page. Once there however, and when they try to click on product photo it then "links" to the page that they're currently on. So there should be some more granularity there.
Okay, that's all I can think of for now. I bet you are sorry you asked for feedback!
I actually have a very rough mockup of what I have in mind if you'd like me to send it along -- I think, though that some of this stuff would be helpful for other people and not just me!
