Nice! I’ve been needing a good CardDAV option. Would you consider supporting Backblaze B2? It’s generally around 4x more cost-effective than Amazon S3, depending on usage patterns.

Regarding markdown to HTML conversion, you might want to check out Jekyll’s templating system. Combined with an Obsidian WebDAV plugin, you’d have an excellent workflow!
