I'm not sure how to use Search for these things so if they've been already suggested (and, evidently, declined for a reason) throw something heavy at me.
Crafting system in Hafen is marvelous, but lacks basic QoL functions. This has been greatly alleviated with a lot of useful macros and hotkeys in this custom client, but still I believe there's room for improvement.
1. Limited quantity crafting. "Craft 1" and "craft all" is good, but how often one finds himself knee-deep in butter, clutching a churn, near to an empty barrel that used to contain 100l of milk? A simple counter of craft iterations in the crafting window would be great. Need 20 butter? Type "20", make 20 butter.
This one would be even more useful considering the recent "craft from a stockpile" perk the devs added.
2. Components crafting. I know the item icons have a function to refer player to corresponding Wiki page (shift-ctrl click or something), but do item icons in crafting window have possibility for similar function? For example, if I open the recipe for Traveller's Sack, can it be arranged that clicking on Hardened leather icon in the sack's crafting window would open Hardened Leather crafting window?
