Use Lets Encrypt to secure preview urls
I think the preview urls is a really useful feature, but they have a limitation in which they cannot be secured.
Being able to secure these urls with a wildcard certificate from Lets Encrypt would be hugely beneficial when developing.
An example would be when developing with certain APIs such as HTML5 Geolocation API.
Thank you for your input. We will consider this functionality in upcoming releases if it is popular. Everyone, please continue voting for this feature if you consider it important.
