I do enjoy using Portfoliobox, this is not the first time I've been using it. But I look forward if someday you would like to improve several features in e-commerce, such as:
1. Platform Integration with Facebook Pixel.
2. Sticky Header. So, the logo would not be gone while page scroll down.
3. More International Currencies & payment gateway.
Thank you for your suggestions! We will let our development team know about all these :)
Regarding #2 you can try using one of the bottom menu templates - the logo would not be gone while scrolling down in the bottom menu design. You can also try our section page, like this one on our demo site.
Hope this helps and have a great week ahead!
