Hey Jerry, thanks for the feedback.

Re: conflicts - I wonder if the conflicts are caused by your other jQuery scripts which perhaps weren't prepared for additional scripts. That's very likely because I've used this module on quite a few sites with A LOT of other jQuery and was always able to resolve those conflicts... If you want, you can post a link to your site (or PM me if you prefer) and I'll take a quick look.

As for the product listing page - I have it working only for cases where you have the "buy now" button, but haven't done it for multiple quantities so I've decided to leave it out in this release. When I get more time, I'll probably add it for all 3 scenarios on product_listing page.

BTW, I've submitted the plugin yesterday, it's now awaiting approval by the Zen Cart Team.
