One domain per line

[jruz]

Hi, Would you be up for reorganizing the domains one per line? Its a bit hard to see the diff and also to scan for domains if they're all in one big line :) I can send you a PR if you'll like something like this.

Thanks for the extension :clap:

It was one domain per line in the beginning but this just created a very long file. Dont really know if it is better to switch back...
