Clutter isn’t really a problem for the devs, it’s more a matter of how the player designs things. Granted, we do need better storage solutions than “dump everything on the floor”, but once that happens, there shouldn’t be a problem unless people let it become a problem.
TBH, I’d prefer if different wood types had their own colour, and the objects made from them would inherit that colour. So the oak furniture in most of the settlement has that same brown colour we have today, but the fancy mahogany furniture in the mayor’s manor that we trekked for hours to obtain had a rich, dark tone to distinguish it. Because if we’re going there for stone, it wouldn’t make sense not to do the same with wood.
I’d also probably do away with the generic “stone” resource. It wouldn’t really make sense among all the specific stone types.
