You can sort the Contacts list by any Featured field that appears as a column by clicking its column header to toggle ascending and descending order, which makes it easy to quickly organize contacts by values like Age or Created On—while keeping in mind that correct sorting depends on the field type (Number vs Date & Time vs Text).

RapidPro.app lets you permanently delete selected contacts directly from the Blocked or Stopped folders (without archiving first), which is useful for targeted cleanup of spam/abuse or opted-out contacts—but deletion is irreversible, so you should carefully review selections and use Archived + Delete All for large-scale, reviewable deletions.
