First launch: macOS may block this release

Version 0.1.0 is ad-hoc signed, not Developer ID signed or notarized. If you trust the download, try opening it once, then go to System Settings → Privacy & Security → Open Anyway and confirm. A managed Mac may prevent this. Read Apple’s explanation.

A box you place by hand

It stays where you put it. If the shared window moves, move the box too.

Show/hide and locking are separate. Hiding keeps its size and position.

Choose any tint colour, set opacity from 5% to 80%, or start with Amber, Blue or Gray. The app remembers your settings locally.
