Sophie, if you need a guaranteed response, the best thing to do is to email our
support ninjas; you'll get a response from an expert in the app you're asking about by the end of the next business day. (Ninjas are also available at 800.315.6664, if that's convenient.)
We all spend time on the forums as we're able to on top of our other duties, but we can't guarantee that someone from a particular team will see a given post in any particular timeframe. I can answer basic questions about OmniGraffle, but don't know enough to answer this one. Sorry!
