Just a couple of points:

1) Make a toggle for the auto pick-up feature. There are times when I want to leave inventory space for what I came to collect.

2) If one can build a storage pile for a material, i.e., wood or stone, then one shouldn't be able to put it in a chest. As it is, one can build a wood pile holding 50 wood or, in the same soace, build two chests each holding 500 wood. Same goes for ancient bark, core wood, fine wood and any of the metal ores.

3) Allow building of trash heaps similar to muddy scrap piles. Throw the stuff you no longer want on the heap and let it sit there. Over time individual pieces should degrade, perhaps even break down into the materials used to make them. One could then go dumpster diving for materials. Toss that iron tower shield in there. Fort the first game monthor two, one could dig it out and repair it. After that one could at least get some of the materials used to construct it.

And I hear ypu already. Number Two would make the game more of a grind than it already is. Number Three? A programmer's nightmare and a lot more overhead for the game engine to keep track of.
