Smart Highlights
What you can safely remove, labelled
Turn a wall of folders into useful categories with clear Safe, Review first, and Protected guidance.

Short answer
Smart Highlights identifies common storage such as caches, developer artifacts, downloads, and personal files. Each match carries a safety label so you can distinguish rebuildable clutter from content that deserves review.

Patterns made for real Macs
Highlights cover everyday files and the storage created by modern developer tools.
