After doing some careful observations I think I can understand why some new players might have a bit of trouble with the UI. Its simply not very consistently organized.
Here is what I mean:
there is even more stuff I forgot to add in the image…
like the fact that storage and furniture swap places from the carpenter crafting menu to the mason and blacksmith
as well as the bird fountain being labeled as a decoration in the mason ui and then relabled as a piece of furniture in the building ui
