Private Admin Notes on User Profiles
Adds a notes box to user profiles that only administrators can see and edit, for things like support history or account details.
Snippet Library
Users snippets for WordPress
Snippets for user accounts, roles and profiles: extra profile fields, new columns in the users list, last-login tracking and tighter control of what each role can do. Handy for membership sites, client sites and teams with many authors.
Record Where Each User Signed Up
Notes how every new account was created (registration form, admin screen, checkout, REST API or WP-CLI) and shows it in a "Signed up via" column on the Users screen.
