I asked the question a few days ago, if there was any way of using an audio file, as well as, or instead of, the text files in Flight School. As there have been no replies, I assume there isn't. As an experiment, I have done this by recording the lesson text in Windows Voice Recorder, then starting the playback manually when the lesson starts. It certainly works, but would be better if you didn't have to manually start it.
Would it be possible to add the facility to save and start the playback of audio files, just like the text files please?
