Since it has become possible to trigger and include new audio files, I'm reasonable sure there could be an audio message included for any time that the TC is deactivated. Something like "Alarm: Fliegerangriff" or "Rauchsäulen am Horizont Herr Kaleun" (like in good old AOD).
We just need someone to do that. Basically I think it's a great idea. Especially on the long and sometimes tedious Atlantic crossings I sometimes wish I could leave the computer alone for a while. Nevertheless I would never go down to TC 64x
