Hey! Some high level thoughts here

We might want this to be a view modifier, rather than an overlay?

I did some looking at this, and saw folks use something like below which might be less burdensome?

Since a view is a struct, i dont think we get any memory issues one shotting the addLocalMonitor ?

 .onAppear(perform:{
                NSEvent.addLocalMonitorForEvents(matching: .scrollWheel) {event in

                // handle event and dont consume
                    return event
                }
            })
