I was very happily using the Picker mod attached below in .13 Factorio but the mod hasn't yet been updated for .14.

It adds the functionality for mousing over an entity, pressing a hotkey, and then having the item you selected go into your hand if you already have it in your inventory (similar to the minecraft middle click, if you know what I mean).

Could someone please update it for 0.14 or teach me how to update it myself?
Thanks!
