Hi everyone,
Following up on this thread from 2023 — the plugin has been significantly updated.
v1.5.0 adds full Cornerstone builder integration: language picker in the builder UI, create translations directly from CS, correct language context in previews, and Polylang Pro compatibility. It now mirrors the WPML integration CS ships natively.
Available on GitHub while the WordPress.org directory review is pending:
