Changelog

0.1.0

In testing

Automatic Sidecar connection at login, with burst retries while the iPad is locked and background watching after that.
Virtual display for Macs with no monitor, so Sidecar can connect at all and Screen Sharing is not blank. Sizes: iPad-matched, 1080p, 1440p and 4K.
Second-screen setup: connect even with a monitor attached, extend or mirror, remembered resolution, Sidebar and Touch Bar.
Always On: keep the Mac awake off / while connected / always, plus Server mode for never-sleep, restart-after-power-failure and wake-for-network.
Reconnects about two seconds after a drop. Per-display ignore list so an HDMI dummy plug does not count as a monitor.
Doctor checks Sidecar support, the iPad, Wi‑Fi, Bluetooth, Apple Account, FileVault, automatic login, sleep policy and disk space.
Optional lock after the first connection, connection sounds, notifications and a plain-text log.
Three-day trial and offline licence keys.

Nothing has shipped publicly yet. When 1.0 is released this page gets a dated entry, and the version on the download page changes with it.
