Thank you for your feedback.
Yes, the settlers will have a more important role in the game like now. My plan is that their daily routine will be completely simulated. In the next update, for the beginning, they will go to a free house and move in.
Decorative objects will be included at a later stage. But I think they are important too. Whether they will be part of the actual buildings or separate buildings, I don't know for now.
As I wrote in a comment above. I will add tooltips and the missing resources to the header soon. I think then will it be more comprehensible for the players.
Yes the save and load system is not completely fine. I have to work on this in the future. If you could tell me what is lost after loading, this would be very helpful for me.
