The MacBook Pro's notch currently serves no purpose beyond housing the camera. Clever developers could create small apps that use this space for status indicators or mini controls.
Build a suite of notch utilities: music visualizers, calendar alerts, timer displays, or file transfer indicators that appear in the notch area.
MacBook Pro users would pay a few dollars for quality of life improvements that utilize otherwise dead space.
Start with a single simple utility (like a countdown timer) to prove the concept before expanding.
Risk: Apple might restrict notch area usage in future OS updates.
