I am really annoying me about the fact you can't set up your island very handy, because you can't store or swap buildings.
I'd really like a 'building mode' as in Clash of Clans, or Family Farm.
With this, all the islands are empty, and you have an inventory, where all of your buildings are listed.
Now you can place all your buildings on the island, save it if you are content, and use it.
You can alternate 2 or 3 presets.
This would really make life lots easier.

Bye and thanks
