Symphony.

A new Extension, “Content Type Mappings” is now available for download. Comments and feedback can be left here but if you discover any issues, please post it on the issue tracker.

Big thanks to @Nitriques for this update (which has been sitting for a long time in the Pull Request queue).

• Allow Content Mappings to be added in the Preferences screen
• Fixes a really old issue reported by @michael-e

Has this extension been deprecated? github link gives 404?

EDIT

Loks like it's moved from Symphonycms account to symphonists. Case closed.
