I have vibe-coded 3 mods that I have tested locally and that other players may find useful:
Game Templates: Allows saving multiplayer game settings so it is easier to switch game types without missing a setting.

Resignation Tribute: Allows you to send resources to allies when you resign.

Quick Lobby: Adds a button to the main menu to get you to the lobby that little bit faster.

I am also playing around with a player notes mod but I am still testing it.
