I think the ability to craft directly from your inventory while you have a crafting table and the ability to bind a key to let you crawl should both be in the "Vanilla Tweaks" section of the guidebook, since they're new mechanics in Crucial 2 that might take a while for new players to figure out. The inventory crafting I could see not including because it's somewhat easy to discover in play, but the crawling definitely should be in the book since you would only notice it if you were looking through all the keybind options. And unicorns should be added to the "Gossip" section, since they're fairly rare and not really connected to anything else in-game, so they're very easy to skip over entirely unless you have some indication that they exist.
