I've added some new functionality to show which items drop other items... So for example, Lush Leaves will now show that it drops Sap, Inky Leaf and Fibrous Leaf. Likewise, if you look at any of those 3 items, it will show that it drops from Lush Leaves.
I'll be going though and linking other items throughout the week ...unless this information is contained in the game files, In which case, I'll just write another import script and you'll get it sooner!
On the cards for a future update will be the visibility of the crafting times for each batch of crafted items, and after that I'll start linking in some crafting progression prerequisites (as they become available!)
