Hide individual flights per-user.

So if I’m at the airport plane spotting and have my laptop or other device with me monitoring FlightAware, there are always a number of flights for which flight plans were filed and never flown, or never closed out, or whatever causes the flights to stay in the list even though they were scheduled to arrive hours or even days ago. You know what would be cool? To be able to hide those individually. Just a little button, and it would make it go away. Then there could be another page where I could unhide if I make an error or change my mind.
