Hi Alex, been loving your caves and mobs mods. Idea: have greyed out animal dictionary book (configurable), have to discover each mob to add it to the book. Either add integration to 'Useful Spyglass', 'Jade' or add your own feature that displays mob name/stats when viewing mob from spyglass. Use the functionality from your wikizoomer mod to render the entity upon keypress while in spyglass and provide the detail text from the animal journal and this will add the entry. Also fun idea for mod compatibility, add in the option to change the mob's picture in the book with an in game photo from exposure or similar photography mods. I have been looking at the code but I don't know Java and it would take me a lot longer to do than you minecraft modding wizards.
