100% agree. I'd go further. As a lord you would certainly have someone tending your finances. I'd love for there to be a page that shows you your trade history, both personally but also for all your workshops and caravans. I don't check my specific income day by day, so I would like to know if my Linen Workshop has been only pulling in 50 denars a day for a while, or if this is just a temporary dip. Is it because the market got flooded, or because the fiefs were raided and they ran out of raw material? If my caravan is making bank, I'd like to see why.
This game has, supposedly, a very complex economic engine, but it is almost completely opaque to us. Not only do we not know what his happening in any particular city, but we don't even know what is happening with our own enterprises. I agree it would add a lot to immersion.
