I am testing your WpStream Theme, interested in purchasing the Friends package.
I would like to understand if it is possible to remove the product page header? If I don’t insert the preview video I am left with the all black header.
You can do anything you want but all depends of your WordPress/CSS/HTML/PHP skills . The theme cannot cover all the needs so each user can change it to fit their needs. Also you can use the wpstream plugin with any other theme.
