This makes Workflowy behave the way I like, similar to my bullet journal setup.

Usage:

1. Install deps composer install
2. Update the timezone setting in workflowy.php
3. Run workflowy.php with your login credentials: EMAIL="x" PASSWORD="x" php workflowy.php
4. Set a cronjob to do so at 00:00 every day

monthly.php generates a pastable list of the days in the current month
