100% agreed, but I think the difficulty is worth it for how much it helps players learn the game. I feel like a solid 70% of my time playing this game is scouring the rulebooks for singular keywords that I see in one place but am unsure how important it is. This game would be impossible without ctrl+f haha.
I think though, if you want to future proof it due to the dev pipeline, just leave out the page numbers. Keep it to just the chapter/section name and the blurb/sentence of why its important. that way while yes you'll occasionally need to go back and change them, its a lot less than every time info changes pages. plus, its most important for the sheets found in the crewed rules and this space intentionally only, so that could cut down on development time a lot.
though of course with all this said, you are the developer and if you think other things need more priority then so be it, the game is still very much playable, just takes longer :p
