I have integrated the new big feature into the inventory system. There’s a lot of new UI that you have not seen yet, but one change to existing stuff looks like that:
The controls are at the top and you can click on the category button (“Tools”) to pick from a list. This is usually much faster than using the arrows.
I am now doing (hopefully) the last thing to do with the new feature: integrating it with the community content. It’s already hooked into crafting and electricity.
