I was thinking that I'd add them, or rather it, when it's actually ready for usage. So for now praise will have to be without Smart Carfter!
@Wiese2007, there is a lua function that starts up the customization process on a hearthling (
homf.customizer:force_customization(hearthling)), however it's not linked to be called from the ui so it's kind of useless for that purpose. But I'm planning on adding a feature like that later on so the player can edit the hearthling's appearances at any time.
