Hahaha, poor Corona Dev's. They deliver pure glory with release 4 and one day after the release, people request the next big thing :)
But i have to agree, that would be a very fine thing to implement. For me it's just important to have a rock solid workflow for stills and also animations. So corona render data should flow easily to PS and AE without many plugins.
Very excited what will come and thanks CORONA! Great Effort!
