- Secure Sync’ing WebDAV compatibility (with Fastmail for example)

I’m sure there are a ton of other reasons, but as new Linux Mint user … having my notes sync across Linux, iOS, & macOS seamlessly is incredibly valuable. Those core features should be the criteria to contemplate any Notes App.
Anything after that might be critical to your needs or how you work or what you work … but to have nailed those three things so well astonishes me, considering the large number of expensive (subscription-based) Notes Apps available today.
