Thanks for the great write up.
One call out, I haven’t fully tested this but it’s good to know.
If you use CloudKit Sync and then edit a file within Obsidian while it’s open in NotePlan the file will automatically update.
If you don’t use CloudKit Sync the file won’t automatically update until you refresh or open it again. Let’s say I have the daily note open in both apps at the same time, I add something to it in Obsidian and then switch back to NotePlan, in NotePlan a quick CMD+T will refresh the note. It’s a minor inconvenience but could potentially lead to conflicting files.
I discovered this issue because CloudKit is blocked on my work laptop so I’ve been trying out Dropbox sync instead.
Also, the NotePlan dev just announced basic ‘Linked References / Backlinks’ functionality will be available soon.
