Product Images + MailChimp Integration
I would love to see a new field for each product called "Product Image". While most people use WHMCS for hosting services, there are quite a few of us that use it to showcase our digital products. I would love a spot to showcase an image and have that enhance the sell value of the product.
In addition, since MailChimp is now integrated, it would be awesome to have this pulled over into MailChimp so that when we send abandoned cart emails it can show a picture of the product.
