Hello,
I would need some help in figuring out how to change the appearance and the position of Printful’s “Personalize Design” button. Currently it has a light grey color and sits under the “Add to Cart” button which makes it very easy to miss. My goal is to be able to change the color of the button and the font as well as to move it above the quantity picker section.

Thanks in advance! 
I am also on a quest to find this out.
@crazy4beer2018 Others would need at minimum a page to inspect.
For any app you want to be sure to check it for such settings like “Theme”, “CSS” “look and feel” etc.
Then reach out to that’s app support or documentation for clarification.
If styling isn’t available from an app then that will require creating custom CSS for the apps elements in a theme.
There have been some previous threads on this but tend to be incomplete or store specific
There may be better luck searching google.
Goodluck.
