I am working on a mod that I am hoping will become big, but I have no clue how to make custom focus icons.

NOTE: I WILL BE DOING EVERYTHING ELSE COMPLETELY ON MY OWN, THIS IS THE ONLY THING THAT OTHERS WILL BE DOING. DO NOT UNDER ANY CIRCUMSTANCES MAKE CHANGES TO THE MOD NOR ASK TO HELP WITH SOMETHING ELSE. I WILL BE DOING EVERYTHING ELSE COMPLETELY ON MY OWN. THIS WILL NOT BE A TEAM MOD

I will likely just credit you in the desc (I will credit you do not worry) but not add you to the dev things for reasons previously stated.

It's the colonial era mod and it's mainly just war/alliannce icons with the flags of the countries eg all the invade things have nation's flags.

Thanks!
