One thing I think he's asking for is to widen the amount of stray that the cross hairs can deviate from their target and still allow the targeting computer to create/maintain a lock. In other words, if the target is moving at a reasonable distance, it's too difficult to keep the reticule tracked so accurately on the target, and you end up having the lock reset and have to start from scratch again. The other thing he seems to be asking for is that once you've achieved lock on, allow the guy launching the missiles to look anywhere else and so long as the target remains on the screen (and not behind cover), don't take the lock off the target/require a button press to manually release lock. Thus, the system would allow you to lock onto one target, and then use dumb fire weapons on a second target while keeping the missile lock and capability of firing missiles at the first target. Is this a more explicit description of what you're trying to say ExMachina?
