The New Codex Feature

What the title says. I noticed this during the Eos gameplay video when the guy briefly goes into the codex. Looks like main missions are logged and given their own codex entries and updated based on the player's decisions. Seems like an easy way to keep track of your major decisions if you forget what choice you made 10-20 hours ago. Go to 16:04 to see it. It goes without saying that the codex entry contain spoilers so watch at your own risk guys.
