Let me start this off by saying that this is really really odd and I'm not serious about this so please don't flame me for this.
If you are annoyed by this style of stupidity/oddity then please go back to the general forum.
Let the suggestion begin :D
I have heard Mr Randazzo say that he hates being fingerprints on dials and screens in FlightDecks so here is a really dumb and random idea;
Make a virtual rag that you can use in your products (that are currently sold) to clean the screens of our virtual flight decks. And perhaps clean up some of the other gunk in the aircraft such as worn paint and grime around different areas of the flight deck.
On the flip side, how about a virtual mud ball to add dirt and "character" to the aircraft?
Ok, I know that it would be stupid to actually do this and this suggestion is not serious, I just thought of the most random thing possible a few weeks ago and this is what I landed on... Again, I am setting myself up for a virtual beating by forum members, and I will cop it but please, don't be too mean.
