Description -
There is currently a robust set of user permissions that can be set up for A/B testing, however this does not extend to recommendations. There is no way to stop any user who has access to Target from editing a Live Recommendations design/critera/collection.
Why is this feature important to you -
To ensure accountability and site stability
How would you like the feature to work -
In exactly the same way the roles and permissions work for A/B testing:
Observer - ability to see, but not edit any design/criteria/collection
Editor - ability to edit, but not publish
Published - ability to publish, but not edit
Approver - ability to edit and publish
