### Expected result

HaGeZi's Allowlist Referral is an ***allowlist*** and it's confusing to place it under "DNS blocklists" when the UI has a section for "DNS allowlist" -- does it mean the intention of the list is reverted, block the allowlist or is it truly an allowlist?

The UI for "DNS allowlist" should work the same as for blocklists, the user could pick from a list of _presets_ (such as HaGeZi's Allowlist Referral) or add their custom.

FWIW, this list is _very_ useful to have to not break shopping sites and referral links.
