AutoExitNode

AutoExitNode is a Windows system tray application that automatically manages your Tailscale exit node based on your network (WiFi SSID or cellular connection).

• Dynamic icon (blue = active, gray = inactive)
• Tooltip with status and active exit node
• Supports fallback exit node names via config.json
• Rate limiting: avoids repeated Tailscale calls if nothing has changed
• Error handling if Tailscale is not installed
• Self-update check against GitHub releases
• Menu to force sync, toggle autostart, check for updates, and quit the app
• Displays running version in the tray menu
