I like using the number pad to hop to different sections of the island but sometimes it skims over different parts I want to see. The in-between parts. Maybe the arrow keys can move you around gently.

Also I thought it would be nice if you double-clicked on a character it could automatically open the DETAILS window for that person.

Trainable kids. When you show them collectables and mushrooms, they could learn to pick most of them up by themselves. Especially when they walk over them like they tend to do already.

Nursing mothers who tell stories to the other kids and therefore get more parenting experience. Maybe they can teach them too.

Warriors. maybe you might need an army to ward off headhunters or cannibals. Obviously you don't have bloodshed. And you do not see the cannibals munching people but maybe you need an army of a certain size to keep the cannibals away and protect the tribe.
If not, you lose a man, maybe a woman but definately not a kid. Thats sad. I didn't like the 6 year old boy dieing from fireants. That was uncomfortable to me because I knew a 6 year old who died from chicken pox complications.
