I'm pretty new to Threads after using Classic for several years. There are a few things that would make life easier:

1) Notice of new registration e-mail to admin should have more information; username, login, UID for new registrant.

2) Approve New Users should list registration requests in order of receipt (in 6.4.1 they seem randomly ordered).

3) Send login information to member button on "show/edit users" admin page.

4) Ability to prevent non-members from using search.

5) Ability to prevent non-registered viewers from accessing members' profile.

6) Ability to include note of explanation in moderator alerts so the moderator can understand the reason for the alert.

7) In Show/Edit user search results, it would be nice to have a feature allowing "display all member's posts" which displayed links and source IP for each post.
