Well, two technically. A gathering and a processing. The gathering skill ought to feel similar to salvaging, and the processing skill should utilize mats from multiple gathering disciplines. As you progress up the tree you unlock more exotic themes for decorations, and indeed unique functions. We have a sore lack of drapery, light sources, and something we have a total lack of is furniture with hooks on them. IE tables with spots to put bottles, plates, desklamps etc.
Basically the furniture we have in game is an eighth of a half measure, and it'd be nice to have a skill to bring it up to at least a quarter measure.
