Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
As of now, FNEI does not show how to obtain an item when it can be obtained by launching (something, aka satellite) into space. I suggest adding the rocket_launch_product and rocket_launch_products to show up as a valid way of obtaining those items... It is not so much an issue in vanilla as it is with angels technology overhaul. I keep getting the question on how to obtain the Gravitational analyzers...
