The main thing this now offers is the Adjust/Halt section; you can enter values for the A and B channels, and the time you want the box to take to change from the current levels to those - and they can be in different directions, so one channel could be going up and one down. Click Adjust and the levels will change over whatever time period you specified.
And if you're feeling bold and want to use this to find out how far you can go, the Halt button comes in handy for that. Enter the power levels you're aiming for, and a long time period, then click Adjust. When you know you can't take any more, the Halt button will stop the increase, but keep the levels at whatever setting they've reached, so you can carry on controlling manually.
