An intuitive Omniture JavaScript editor to customize the s_code file according to the variables / events / properties in place would bring a huge value to marketing people willing to quickly translate their business requirements into a concrete change to the tracking structure without having to get technical.
Making the technology more transparent is a common trend these days and "Marketing Channels" feature clearly is a good example showing Adobe's wish to make their clients' day-to-day activities easier. . A further step would definitely be appreciated.
