Graal (some Holy Graal event chain, I didn't look inside due to spoiler warning).
Declare Friends and Rivals (more control over that system).
A New Holding For Capital (can build up to 6 holdings in your capital county, very expensive).
a few more Council Members (if you have council empowered).
Battle Prisoners (very high chance to capture commanders in lost battles).
a few new CBs (de jure duchy CB, and abolish title which is de jure over part of your land) based on Workshop mods with some tweaks.
my set of usual CK2 tweaks - too long to list, but especially much more reasonable vassal limit.
This time as Charlemagne, with a lot of mods, might be OP or broken or something: Maximum Gavelkind: Part 01: January 769-May 770: The First Conclave War
