I made a feature request during the early alpha and beta phases to be able to see the Summary information inline on the Narrative Outline view. It seemed strange to me that this was not possible for software which has the ability to plan a narrative outline. In answer to that feature request some users pointed out that syncing between AT3 and Scrivener would generate an outline which was printable. But for users who do not use Scrivener, like me, this is not an answer.
Moving on nearly two and a half years and I feel the need to be able to access narrative elements outside of AT3. There is the option to export to PDFs and images and to CSV/ TSV and Timeline Formats, but for me, as a writer, who works with words, these formats are next to useless.
Opening up the export function to allow text-based exports to docx files or RTF(D) files and preferably also Markdown, would also allow users who write in Word or Google Docs to be able to get to the narrative information they are building inside AT3. It would also get around the issue of sending character information into Scrivener and Ulysses. Rather than handle this through the Sync mechanism, character info could be exported and then opened inside other writing apps.
AT3 is excellent at handling data and seeing connections between the different types of data. Where it currently falls short is in the textual handling of ideas, general sketches, notes and narrative development. I am currently doing all of this kind of work inside Ulysses. And perhaps this is the best place to do this kind of detailed narrative exploration as a precursor to generating a list of scenes. However, I think there is an expectation amongst most users that the software they are using to plan their stories should also allow them to export their plan to a text format.
