Allow for the tiers of crafting and refinement benches/items to be simply upgraded by inputting higher tiered components instead of making a player destroy the crafting bench and then replace it fully with the new one. This will help reduce the random items that accumulate as one progresses through the game (ie, I have random crafted parts that were part of my refined benches but weren't used in my excellent ones and those components are just sitting in a chest taking up space until I go around and turn them into dust).
I can't begin to tell you how badly I want to be able to upgrade things rather than have to tear down and replace. We went from a Crude house to a Stave house and in every room have to move everything... EVERYTHING to replace the floor, walls, ceiling.. etc. Even if we can only "UPGRADE" using the hammer. I really hope that upgrading happens!
