I just found a Mac app that puts volume and brightness sliders on your MacBook’s touchpad edges

Slidr is a new Mac app that turns MacBook trackpad edges into gesture zones for quick volume and brightness control.

The right edge adjusts volume, while the left edge controls brightness; it also adds options like middle-click gestures and fine tuning.

Users can swap sides, limit gestures, and freeze the cursor, making it a flexible touchpad-based control tool.

Slidr offers a short free trial and then a one-time purchase, appealing to users who want simpler controls without a subscription.
