When clicking on a ship, a taskbar button will allows us to choose whether this ship will target mostly repair ships/long range or missile ships/skirmishers/strongest capital ship/support capital ship/buildings. That will be just great and allow us to truly leave fleet battles in the hands of the AI and deal with other tasks elsewhere.
A simple selection like this makes sense, and could be implemented simply by putting some of the game's internal AI workings/weights into text files (I recall homeworld 2 having priority settings for each ship type). Having to script AI would be just too much work for the vast majority of players
The configurability would need to be assessed, because the community's gameplay changes and some options might just become useless. Flexibility game-per-game or between different battles could be a good thing, so in-game GUI might be the way to go. For those that mostly play AI, a static textfile would be enough.
@anticommie: AI is plain stupid, yes, but humans have some features that you might use against them. The Boiling Frog for instance: jump in the cap ship, and most players will keep hammering it even if you jump in a couple of hoshikos after the cap's shields are gone. The enemy won't notice they really are screwed until the first hoshikos have depleted their AM and you jump in 8 more, together with some other reinforcements...
