hi,

I have tried this mod, and it is great.

However, there are some suggestion which may make it better:

1. Is it possible to put a link in the cart page, which link "Edit Product Option" just besides the product name or else where.
However, the link is NOT link back to the product page, it can be a popup page, and it only show the product option.
so that buyer DO NOT need to go back to the product page and reload the whole page.

2. if using the 1 suggestion, there is no need to worry about the SEO link problem.

3. if using the 1 suggestion, there is NO need to modify the cored product info page, else well else the shopping cart tpl.
it is supposed to add ONE line like this:
<a href="update cart page url">Edit Product Option Here</a>

sorry that i don't know too much php, but i guess it is more easy for the future upgrade and modification.

hope Justin can take my suggestion in the new release.
