I'm testing Sellacious on my web site and have found a few minor problems with how the cart appears. I fixed one of my problems by changing the width of the item count field in the layouts/com_sellacious/cart/aio/items_modal.php from your 30px to 100px. (30px is waaayyy too small, why did you pick such a small size and then hard-code it?)
But I'm onto the next -- and final issue -- if this gets fixed I'll be happy to purchase Sellacious and use it on my web sites. Here's the problem:
After selecting an item for purchase, I get the 'pop-up' cart page that shows what's in my cart along with the new item. The background on this page is wrong... Sellacious seems to be picking this color up from somewhere, but it makes it impossible to read the details on the 'shopping cart'. (Attached is a pic of what's happening) .. FYI this problem existed before I made any changes... so it's not something I introduced.
