Pin a quest and track it on the HUD while you play. Progress updates as you go so you rarely open the book.
Early quest tree shown with an example pack. Chop logs, follow the lines, claim your food. Tenet itself ships empty, you build the line.
Same view whether you have ten quests or hundreds. Shown here with a large example pack to prove it stays readable.
Open Edit, click a quest and change tasks and rewards right there. No restart and you can undo if you misclick.
Tune colors, borders and background for the whole book or a single chapter. Shown here with example content.
