Players have for a while now been able to give both move commands and attack commands to ships, but until now haven't been able to queue up multiple commands or tweak commands already-given. These two new features really help make commands more flexible and useful.
Queuing up multiple commands to be executed in sequence is easy. Simply give the first command and then hold the shift key while giving each additional command. It looks like this:
Adjusting an already-queued command is also pretty easy. While holding shift, rotator and mover widgets will be displayed. Simply click and drag on one of the four arrows to rotate the ship, or click and drag the center widget to move the ship.
This also of course works for attack commands too. Clicking and dragging the center widget will adjust the distance and direction of attack. Clicking and dragging one of the four arrows allows you to choose what flank your ship will fire from, which was previously not able to be manually set.
