Haptiker
Volume, brightness and app switching from the trackpad's edges.
About Haptiker
Haptiker turns the four edges of the trackpad into sliders: the right edge sets the volume, the left edge the display brightness (external monitors too, over DDC on Apple silicon), the top edge the keyboard backlight, and the bottom edge switches apps. Guards stop accidental swipes, and haptic ticks confirm each step. No account and no analytics; needs macOS 12 or later and Accessibility access.
