(yes, another AIR success story, but it's mine :-) )
My wife and I are lucky enough to get the same train in and out of the city, and it was on the journey home on Friday that she mentioned some work flow changes in her office. The upshot of these changes was that she was having to look at raw XML files many times a day.

I foolishly mentioned I could probably knock something up 'in a few hours' to make this a lot easier.
