This is a great opportunity to make AI ships more interesting or acting differently in specific cases.
Here you can find a mod experimenting with that:

AI ships will now pursuit the playership through gates !
I made also another modification from the original behavior, AI ships won't gate out, but will start wandering around the system, until they will find something else to pursuit (like the player returning

What do you think ? What kind of ship behavior would you like to see ?
