If there’s time (possibly as part of 1.1), I’d definitely second the request to juggle around where fibres go. There’s also the issue of wool coming under “animal parts”, which is very situational (most people will just keep all their animal parts at the weaver’s house…) but can be a pain if someone wants to use containers near their trapping zones to collect and bulk-move all those pelts.
Making “animal parts” into just “pelts”, and having a category for fibres, would neaten things up quite a bit.
If that goes ahead, I’d also like to suggest splitting up varanus skins and insect shells; so we could have “pelts” from furry creatures and “hides” from anything else. It might seem pedantic, but again it comes down to the fact that varanus skins are used by the herbalist (and very rarely the mason) while everything else goes to the weaver. I don’t believe the shells are even used for anything, but they don’t seem to belong with the soft pelts and if they do get a use I doubt it would be the weaver using them hahah.
