A new item that makes it so you can cut walls, roof tops, floors and more, since most of tem are a 2x2, make it so you can have 1x2 and 1x1 of them
A new toggle option that makes things that are placed automatically be hammered so you cant move them again
A item like a table that have a hole that fits perfectly a bucket, you click with a Q in the table and it puts the bucket in the hole automatically, for when you have something like a drill but not a harvester in early game or a auto cutter later
Something like a anvil that you craft that have like an furnace thing "inside" it that makes the ores be auto heathed when placed in it for crafts
A shelf where you can put ore bars, things you craft in the anvil, the modules for crafting in icehelm, artifacts and more
Something that shrinks you when you interact with so you can walk in a 1x1 space without having to crouch
A ingame computer where you select items either to say where you can buy or to as for delivering it to your house
A price chart for every raw ore, raw gem, craftable, ore bar and polished gem (one for each for compact reasons)
A blueprint thing, where in it you can select different items and construct as much as you want with it without worrying with the items, and when you are done you put it in some kind of board that shows you how much of each thing you need to buy to do that thing
Being able to have equippable things, such as running shoes that makes you 1.5-2.0x faster, crafting jetpack that costs shard bar weights to make you fly (probably crafted with a lot of cloutium and some onyx for being mid-late game)
