I have a ToC file for books. If I want to rearrange scenes, I just move them in the ToC and don’t worry about the folder order.
Obsidian is already more powerful than Scrivener, and the Mac and iOS apps offer both fast syncing and, most importantly for me, full cross-platform functionality. With Scrivener, the iOS app is severely limited.
Obsidian also has the advantage of using plain text / MD, making the files easily accessible and editable in other apps, unlike Scrivener’s hidden RTF-based projects.
It is easy to import files from Obsidian to Scrivener, but the need to do that is diminishing as Obsidian leaps ahead in terms of features and the speed of progress.
And Obsidian lets writers develop works along multiple paths and in multiple directions at the same time. Scrivener has a more linear approach. I didn’t know an app could change how I think and then write until I used Obsidian. Liberating.
And Obsidian has more than one (Mac / iOS) developer and a whole community of secondary developers creating plug-ins. It’s in another realm.
I have used and loved Scrivener since the Mac beta, but Obsidian is just so much more powerful these days.
