Collapse domain aliases under main domain
When you have a domain with many aliases (I currently have one with 15 domain aliases and several with 4 or 5) it makes the classic view (or any other view for that matter) a bit messy.
It would be great if these domain aliases were simply hidden from the list using an accordion or something below the main domain so you can expand it out if needed.
They also shouldn't count towards the number of domains shown on the page e.g. 25.
