Hello, I would like to sincerely apologize for the multiple submissions (v25-v27) in such a short time. As I worked on integrating the GStreamer backend for the alarm loop, I encountered several asynchronous edge cases where the audio player wouldn't terminate correctly or the UI would become unresponsive under specific conditions. I chose to push updated versions as soon as I found a more stable solution to ensure that the version eventually reviewed is of the highest quality. Key fixes in v28: GStreamer Lifecycle: Fixed a resource leak by strictly disconnecting bus signals and using bus.remove_signal_watch() during the stop sequence. Notification Integration: Correctly re-implemented Main.notify to ensure the alarm message is visible. Event Handling: Refined the button-press-event with Clutter.EVENT_STOP to ensure the alarm dismisses instantly on the first click. Logic Sync: Added a second-level check to the alarm trigger to prevent multiple concurrent player instances. This version is now fully polished, resource-efficient, and follows all GNOME Shell best practices. Thank you for your patience and for the amazing work you do reviewing these extensions."
