Haven't tried voice attack or any of the similar speech-to-text programs with RoF - it might work, if the program plays nice with RoF, but I suspect some might and some might not. Would certainly be handy 'cause typing into chat is pretty disruptive when you're trying to fly.
There are several realism settings relating to icons, both on the map and on the planes in flight in the game - I don't use any of them and don;t know how they work, but I'd suggest that you try reading the manual - it's quite complete and I bet there is a section explaining how those icon settings work. Of course, in MP some of those icon settings may be controlled by the server so you may not be able to use them in certain MP games, but in SP they should all work if you set them up in your settings appropriately. Also, even when you tick them in the options/settings screen, many of them can be toggled on and of while in game, so if you have them set but still aren't seeing them try hitting the key commands to toggle them on while you're flying in the game.
