I'm not entirely sure how much work this would require but I had a couple of ideas for the Codex.
A Crew/Major NPCs Section - Contains Bios and description with their personal encounter log items attached at the bottom.
A Spacecraft Section - For named and general spaceships.
New Fiction to be unlocked as you complete Codex Sections. Example, Unlocking all the Tarkus entries would unlock the story Bull's Strength. I like the idea of the Fiction being a kind of reward.
These are just ideas
