Pop Convert ‑ Pop Ups, Banners

Great App, and the best part is that it's free! until now it's working well.. but it would be great if the subscribers appears under the "customers" shopify dashboard section.. also it would be great if the setting "after closing" popup propose more timing options, because we can just select "7 seven days" or above once closed the popup.. anyway! I hope it will remain free for ever!
