Unofficial web extension created for queueing system QMATIC Orchestra to get sound notifications in queue.
This extension works by observing queue number - how many people are present in the queue. When the queue gets bigger, the extension takes note and plays a sound. At this moment the extension observes only person queue, not workplace queue.
The extension was tested on QMATIC Orchestra 7.0. If you have any suggestions or any kind of feedback, please feel free to email me.
