Here is what I added today : 

- it is now possible to add and use items from a hotbar

- inventory, equipment and scraping menus are now textless (they rely on the tooltip to show the item's name)

- items now have a durability (they break after some time, typically equipment and tools)

- it is now possible to craft Tools

- Since a hotbar was added (and keys 1,2,3,4 and 5 with it), input is now only wasd for moving and space for waiting
