It would be fantastic if this supported email and calendar providers that weren't Google. Supporting protocols like IMAP or JMAP alongside CalDav would be a fantastic step, as well as open source note-taking apps like Hyprnote would be neat.
I second this, as a big Fastmail user
Agreed 100% and we'll slot these into our roadmap. We started out with Google because it was the fastest. Will definitely look into Hypernote integration as well.
