No worries! I mean it's all the same thing, just the matter of stylish presentation. The real nut would be that checking in on nobles' activities could give clues to what's happening 'at a glance.' I agree that some sort of pop-in 'Hey, Player! Try gathering webs!' is not quite the style that Dwarf Fortress is going for. Perhaps 'Urist is concerned seeing most of his subjects are unclothed' is more in line with The Style Guide. The real nut of the idea is that nobles could be used to allow the player to generalize and make their play more abstract if they so chose. So in the OP I listed a couple fictional noble roles- these could be entirely optional and up to the discretion of the individual player. Let's say I don't like dealing with food, my *pantry lieutenant* could be in charge of butchery and stuff.
As the above poster mentioned, maybe a soft mandate option could be listed in the Nobles screen- recommendations or something like.
The very simplest implementation of this idea, now that I'm thinking of it, is with the broker. Considering how often I forget what my export agreements look like, it would be nice if the broker reminded me of it through soft mandates. I try to role-play a savvy commodities trader, so it would be cool if the broker would say something like 'the mountainhome would pay a premium for goblets, let's make goblets.'
