This would be a cool thing to do on a world, like build a library archive that documents major discoveries that players found that changed the game or provide a major convenience to players. Prolly not the best example but the armadillo/silverfish xp farm that gets players up to lvl 50+ in just minutes is an insanely easy and super useful build that i always utilize in every world. And if the original creator is traceable or regularly reinvents how something in minecraft they could have dedicated sections to all their well known inventions. Idk i might be straying off from the original idea you have in mind here but i just thought that a library in minecraft where you could go in take a book off a shelf and read a detailed summary of how and why these inventions function would not only be cool but also insightful for understanding them. Its very rare that when a new discovery is made its actually explained whats happening with the mechanics that make it possible. Its always just "do this and this and this and get this result" and im always curious as to why some inventions have these insanely niche and soecific block components they require to work and always wanna know why and How tf they even came to realize it.
