I've been maintaining a native macOS menu bar app called MacPilot and finally open-sourced it: https://github.com/misswell/MacPilot

It's built with Swift 6 + SwiftUI, has zero third-party Swift dependencies, and ships as a notarized Developer ID build.

What's inside:

Per-app quit rules: hide / close windows / quit an app after it's been idle for N minutes. Chat and mail apps stop stealing attention automatically.

BLE proximity unlock: unlock your Mac when your iPhone or Apple Watch comes close, lock when it leaves. RSSI smoothing plus dual thresholds, so a flaky signal doesn't flap the lock.
