Lovin-SticknTee review for Qikify Custom Product Options

This is exactly what I was looking for and the configuration is so easy. However, I have two small problems that I would like to solve, but in my opinion nothing serious. The first: when I activate the customization option, the css style of the "add to cart" button is modified which is not aesthetic. The second, by default the customization field is displayed between the "size guide" and the "quantity". Can we choose another location? Thank you!
