- Apps for, at least, windows and android.

- Storage of files in a folder that can be seen by the OS to allow sync by something like syncthing

- Moderately good UI (nice to have: live preview of markdown)

- Core features not behind a paywall (e.g. siyuan can't sync, notenook missing important features)

- Nice to have: push notifications for tasks/reminders
