### The problem

Finding if a domain name has already been added in the Ignored Domains section of the settings, UI is tricky when you get past, say, ten as they are in whatever order you entered them into the box and not sorted.

### Proposed solution

Sort the Ignored domains section alphabetically by the domain name to improve searchability.
