Modify WooCommerce Plugin

Hello everyone, The purpose of this project is to update a WooCommerce plugin we had modified in the past. The plugin name is Fancy Product Designer ([login to view URL]). The modifications needs to be ported to the new plugin version. There are also two new options we want to add. Here are all the modifications needed: 1) Make the plugin compatible with Amazon Web Services / WP Offload S3 Lite plugins 2) Prevent blank products from being added to the cart 3) Add an option to fix the price of the first image/text/design 4) Add an option to set price rules based on product category 5) Make an existing option available elsewhere within the plugin Options 1 and 2 are already working in the modified version of the plugin. Options 3, 4 and 6 needs to be added (new modifications) There was also two custom options that we added: "Charge elements only once" and "Charge only the most expensive element". These options are not needed anymore as the latest version of FPD introduced a "Maximum price per view" option so you can ignore these. Detailed instructions about each options are available in the documentation attached with the project. Please make sure to read it as it contains important information and link to our staging site. Note that we will need a report of the modifications you've made so that we can forward them to the original plugin author. Please make sure to details the following: -The name of the file(s) modified -The start and end lines of code modified/removed -What the modification does Looking forward to working with you!
