Hi Erica,
thanks for the clarifications and making it clear that outlining is not part of your roadmap. Is there any document/thread that states your vision for Obsidian aside from the website homepage and the trello roadmap ? Even without adding complete outlining to Obsidian, would you still consider adding folding in the preview pane in the near future ?
Mindforger (Github link to doc) (it is also an offline/local md editor with some backlinking and autolinking features) can turn markdown sections into outlining. you can’t link to a specific section in a note but it is still useful to get an overview of the content.
I’ll probably stick with Mindforger+Dynalist for now but I hope Obsidian will grow to be a viable replacement.
