Easier Quantity Input on Product Pages (+/- Buttons)

Currently, on DecoNetwork product pages, customers must manually type numbers into the quantity fields for each size.

We would like to request a native feature that adds "+" and "−" buttons next to each quantity field so customers can easily increase or decrease quantities with a single click.

Reasons for this request:
- Improves usability, especially on mobile devices
- Reduces input errors
- Makes bulk ordering by size much easier for schools, teams, and organizations
- Aligns with standard eCommerce UX found on Shopify, WooCommerce, and other platforms

Ideally, this would be a built-in option in the Product Page settings such as:
"Enable +/- quantity buttons"

Thank you for considering this feature request.
