MacEdge turns the unused edges of your Mac trackpad into controls. Slide the right edge for volume, the left for brightness, drag the bottom to scrub any video, and tap the top corners to open apps, links, key combos or Shortcuts. The middle of the trackpad works exactly as before, palms and scrolling never trigger it, and every step has a haptic tick. Native Swift, Apple silicon, macOS 14+. Touches never leave your Mac. $3 once, no subscription.
