I'm thinking about moving my Nextcloud calendars and addressbooks to Baikal. Why? Because I like one "tool for one thing" better than "one tool for everything".
Small update: Today I moved to Baikal successfully.
It's missing some features, I noticed.
- There are no shared addressbooks, so a shared user is needed. Addressbooks also cannot be read-only.
- There is no birthday calendar. There is a Python script for MySQL to run from cron. I ported it to PostgreSQL today.
