One of the most frustrating things is seeing a little island full of resources, and unable to reach it. A ferry or even better, bridges should be perfect implements.
Also a are of effect for the wells when you put it down would be nice.

Welcome to the forum.
You can turn off raiders/predators by choosing the Pacifist option in the Advanced Settings when starting a new town.
Wood bridges would be great for sure!
