[*] Need a way to sort the inventory
[*] Would like a recipe book for things I know how to craft.
I'd second both of these.
Over time I'm accumulating blank squares in my inventory screen as it refuses to re-sort after I lose items. It's also a shame that some of the crafting specific items (e.g. a knife to cut various items) don't appear on the ingredients screen. I understand why this logically is the case, but certain crafting actions then have to take place in the all items view, along with dragging items around so they appear in the same screen...and all the blank squares.
I'm keeping a text file with recipes as I go, but it would certainly make sense that after you've crafted something once it becomes learned and appears in a crafting screen somewhere. Either for reference (another tab on the map/secrets screen?) or as an actual crafting interface to one click if you have the required ingredients.
