Dear Developer,
First of all, I want to say that your plugin is perfect for Custom Fields Before Checkout in EDD.
Here we need some help from your side.
is it possible that in this Plugin you ADD the URL field? (only specified for URL field). Customers will only add URL links, not add other contents in the field. Check Screenshot: https://ibb.co/x2YRHyz
And 2nd thing is your Plugin is not updated as per WP new version.
Thanks`
