I think the game has been around long enough that rotating buildings should have been introduced. Bored players have nothing to do sometimes other than rearrange or decorate their islands. Unfortunately, the unidirectional buildings/decorations just don't make any sense to even try to use for decoration.

Put the BB creative dept to use and pull out those models (I'm use they've already been created), polish them off, and get them in the game. Start off with decorations and non-upgrading buildings.

Please.
