Hi diggle ,
We don't plan to add capabilities to Action Logs, sorry.
Anyway, you can use the Role Editor to hide the action logs menu from your employees. Of course, you'd need to make sure they can't either deactivate plugins...
Please, note that other plugins can change the stock levels, and Action Logs won't log it if they don't use the standard WooCommerce functions to change it.
Best Regards,
José Andrés
