I helped found this project, originally a simple modification for the A320neo that shipped with Microsoft Flight Simulator (2020). It has since grown into a pretty complex open-source add-on with dozens of contributors - something of a rarity in the flight sim world where the norm is either payware or closed-source freeware addons. Here's the link to the repo:
