I will admit upfront I have little knowledge of the Deep Lore when it comes to Factorio modding, but would it be possible to add a UI button on merged chests/warehouses when you open them to sort them? I remember reading a while back that sorting chests like that automatically would be a performance killer, but if it would be possible to add a button for an on demand sort, that would be awesome. No idea if it's even possible and if it's not, that's no big deal. :)
