This PR enables physical scroll/tilt wheels (like the Logitech MX Anywhere 2 left/right tilt) to function reliably on macOS even when Ignore trackpad is enabled, and adds support for ultra-low horizontal scroll thresholds to eliminate delay when triggering mapped keystrokes.
Key Changes
core/mouse_hook_macos.py, we inspectkCGScrollWheelEventScrollPhaseandkCGScrollWheelEventMomentumPhase. Trackpads and Magic Mice always generate gesture events with non-zero phases, while traditional mice/tilt-wheels do not (both phases are0). We now verify if these phases are non-zero before filtering, letting physical wheel tilt inputs pass through even whenignore_trackpadis enabled.core/engine.py, we lowered the minimum threshold cap to0.01(from0.1), allowing users to specify a threshold like0.1or lower in their configuration. This fires mapped actions instantly on the very first tilt event.hscroll_leftandhscroll_rightusing the"mapping"type instead of"hscroll"incore/logi_device_catalog.py, allowing them to be mapped separately in the UI.core/config.pytype validation to allow floats for numeric default config templates, and updated the mock setups intests/test_mouse_hook.pyandtests/test_device_layouts.py.
