Ultimatum / More diplomacy options?

[Gregor Hermann 2]

Good evening, @Łukasz Jakowski.
as in title, are you working on adding more diplomacy updates such as ultimatums or trades between nations?

Thank you :>

Something like sell some economy of a province to another country (like the "explotation" mechanic, but asking X amount of money) would be great.
And selecting easily the provinces to sell.
Idk, I just say.
