docktor: live window previews and widgets on the macOS 26 Dock

There's dead space on both sides of the Dock. Nobody uses it. So I stuck widgets there. Music with synced lyrics (Spotify + Apple Music), calendar, weather, a Pomodoro timer, system stats. They sit in little glass panels and stay out of the way until you look down.

The other thing: hover a Dock icon and macOS shows you the app name. Thanks, I forgot what Safari was called. Docktor replaces that with live thumbnails of every window for that app. Click one, you're there. Same idea powers a Cmd+Tab replacement. Actual window previews instead of a beauty pageant of app icons.

I spent a lot of time matching the system look. Same blur radii, same animation timing. It should feel like part of the Dock, not something bolted on.

Native Swift. No Electron, no account, no telemetry.

First beta goes out next week. Looking for testers: https://petercsauer.github.io/docktor-releases/

Testers get lifetime access free. After that it'll be $10 one-time for 20 seats, 60-day trial
