Firewall Front-End Design

Hi, I have a lot of domains to ban, mostly from tracking/analytics/ad/marketing. While the present interface is fine, I can see it becoming very unwieldy as the list grows. I’ll leave the front-end design to you experts on how to make this flexible+sortable but could you perhaps incorporate an import/export function into csv, etc.?
