I have the world tool and it does change the labels. The only issue with their tool is the timing. You can tell that your working on a new laptop that's plug into an old microprocessor(I guess that's a good way to describe it). When you change displays you have to wait for the software to catch up. And when your moving through groups and bits you have to get your timing right to get the "focus" where you want it to make adjustments, but once you've done it a couple of times it's fairly simple.
