Me personally, I have hundreds of Minecraft files, creative, survival, I think there should be a search system, to search by name, creative, or survival, it would be a very handy system for someone like me, I don't know how hard this would be but I really don't think it would be to hard to implement, I'm no game developer or have any idea on how coding works, but too me it seems like something that should have been there since the start.
The abillity to search through Minecraft files
