New function: It is now possible to find out in which rules a field is used!
In the Rules step of your feed or API you can now easily see which rules use a specific field. In the top bar of the rules click on the search icon and select which field you would like to search for. If the field is used in the rules the format of the rulename will change to bold and next to the name you will see a blue dot. If the field is not used in any of the rules you will see the message "Field not found".
