I’m honestly not sure how universal this is, but for laptops, I make a lot of use of the pinch and reverse pinch gesture to zoom in and out. And there’s no way to synthesize a pinch from other inputs. Are there any plans to include this event in GLFW, similar to the XY scroll event?

Thanks for any insights,
