Remove suggestions if they're in the game

I keep going through the Feedback site through the "announced" stuff, and a lot of what I'm seeing is already in the game. You marked it as "Announced" because you thought it was a good idea, but once you added that idea into the game, you don't bother taking the post down. Like the "Add Biome Locate command" Feedback is still there under the Announced section, even though you already added them in the game.
