Great feedback.
- Daily notes - not there yet but it's a straightforward feature to add. I'll put it on the roadmap.
- Templates - same, noted.
- Sync conflicts - fair point. HelixNotes watches the filesystem for external changes, but conflict resolution when two devices edit the same note is a real problem with any file-based sync. Syncthing handles this better than most (it creates conflict copies instead of overwriting), but it's not perfect.
If you end up trying it and want to contribute, open issues on Codeberg for what you'd like to see. Contributions are very welcome.
