Helium Customer Fields

Great app. for customer data management. I installed this app. to build our customer data base for my business. They provide free install service and it was very helpful to me although I do not have any programming skills. One thing I would like to suggest to Customer Fields to apply indicating mark of each required fields in create account page. I created so many fields but some customers do not like to fill out all of my fields, and I would like to offer to required field and optional field option and it would be very helpful for improving customer account registration.
Any how, it would be the best option in Shopify app stores.
