Add an achievement for crafting Ender Compendium to encourage it a little bit more.

Open the Compendium while looking at a block, item or mob would show the corresponding fragments - try to make it work with worldgen structures too.

Perhaps add additional info to blocks and item in the inventory if you hold shift and have appropriate fragments in the Compendium, just so it's a little easier to remember stuff.
