This is very cool. If you're working on more, I would love something that lets me favorite a particular good's price, and be able to see it on screen as a I play, both the price and the price as a percentage of what it was in a particular year. So if I start selling oil and the price collapses, I know to keep it in storage and vice versa. It's hard to keep up with price fluctuations in the game.

I missed watching th introduction video in the first place. Thanks for that.

Great work, they should add this to the base game.

Yes, they will still work after saving and loading.

Really cool! Are the observers stored in the save file? Do they work on save/load?
