Thanks for that! With regards to your last paragraph - that is the biggest reason I started using Longform. Drag & drop reorganizing of scenes is incredibly helpful for me. The major benefit I see doing things with headers in one MD file is the ability to leave header areas with comments. I still haven’t found a great way to add comments for revisions and such and currently just add them to my Kanban board for revision tracking… but what if I forget where I wanted to change something? I use brackets in-text to denote placeholders but sometimes you just really need a comment on a section. I guess linking the text section to its own page for comments would work, though.
I hope a true comment system will be added eventually because that and word goal tracking are the biggest missing features for writers IMO. The corkboard thing is easily solved with your Kanban board method so I’m not as concerned by that one.
