Excellent work. I would give an arm and a leg to be able to replace the existing touchpad in my Framework Laptop 13 with your upside-down ThinkPad touchpad. Unfortunately, I don’t have the technical knowledge and equipment necessary to do this myself. I hope that this mod in the future becomes more accessible.
Alternatively, I hope that Framework in the future will provide an official touchpad module with discrete buttons. I made a post here to request this feature.
