Kill me if I'm reposting, but there looks to be a Google AdWords editor update that's just come through. Seems to fix up a lot of the minor limitations it had previously. I'm still having a play around with it at the moment but hopefully it's a few steps closer to increasing workflow! If you don't have it yet, get it here: http://services.google.com/adwordseditor/ If you've already got it, it should pop up with a message saying there's an update available.
It's great! It's been great since they've added a Keyword Grouper tool and a Duplicate Keyword Tool, it seems Google's really on the ball with what we want. It also looks like they've taken out some of the ad stat columns that never worked which used to clutter up the ad list.
