Thanks for your comments and we’re glad to know that you liked the free version of our plugin. We have a lot of users with different themes using our free and pro version of our plugin.
Regarding your comment -The class attributes or other HTML attributes may break the checkout page frontend- We use the same classes that are used by Woocommerce and added some additional classes with our own prefix (these classes are not associated with any styling). If the free version of our plugin works, then the pro version will also have no frontend issues. There may be chances like, your theme not supporting Woocommerce class styles like form-row-wide, form-row-first and form-row-last. Also there are some plugins that add their own checkout fields with priority values. In this case also you can drag and adjust fields from backend settings.
Regarding the comment -The fields cannot be conditionally required- We already mentioned that we don’t have an option to make a field conditionally required, we only have the option to show/hide fields conditionally. And we don’t think any other checkout field editor plugins have this conditionally required option.
Regarding the comment -It displayed an “Array” on the order summary page instead of each field separately. Same for the order email- We are saving extra fields options as a single meta data. But It will display as a separate field and its value under the corresponding sections on order summary and order emails. This may not make any issues. If you want to retrieve a single field value then it can be retrieved using the order number. Also we are hiding this extra field values from the custom fields section on the backend order detail page.
