I would love to see mentors in a future version. You set someone as a mentor for a child and the child will follow him/her around and "learn" from them. As many others have said, I'd like to be able to easily track genealogy in the game itself. I like the idea of the collections, but perhaps make them tie back into the active part of the game. For example, collect so many bees to be able to pollinate a certain fruit tree or collect so many pebbles in order to learn masonry and be able to build stone features, etc.
