This app monitors your Steam gaming activity and automatically updates your Steam Friends status:
🟢 When you start playing a game your status is set to Online
🔴 When you close the game your status is set back to Offline
The application uses Windows registry change notifications to monitor the HKEY_CURRENT_USER\Software\Valve\Steam\RunningAppID registry key (to check if AppID = 0). When Steam launches or closes a game, the registry value changes and triggers an event, which the application responds to. This event-based approach means the application only runs when changes occur, not constantly polling. It uses the Steam browser protocol (steam://friends/status/...) to update your status.
