Thanks for your feedback. The font can be controlled in the cart using the module.css in \desktopmodules\smith.buynow\module.css. The class the controls the font in the cart is the following:
.SmithProdtext
{
font-family:Verdana, Arial, Helvetica, sans-serif;
font-size: 12px;
color:#000000
}
If you setup product variants you are able to upload multiple images per product but we will add to the development list multiple images for non variant items on the product details page.
Automatic generation of the thimbnail images is #1 on the development list.
