Allow a user to copy their island into the planner.
1. It is a painfully slow to have to add each building individually.
2. Then you have to remember to update if the building
3. or is leveled up
4. or a building is moved
5. Users can then move buildings around to find best production locations.
6. or how many building types are need to achieve a required level of production.
7. provide reset facility to re-copy at anytime.
Should be low cost to provide, you already hold the data? Benefits to users would be enormous.
