This is the community forum for my apps Pythonista and Editorial.
For individual support questions, you can also send an email. If you have a very short question or just want to say hello — I'm @olemoritz on Twitter.
This sounds a lot like the other HogBay software project, FoldingText. http://www.foldingtext.com/
There isn't an iOS version and I think if Editorial could handle FT documents it would be awesome.
