Promising, but very sad UX decisions

A single administration page listing all users that exist,
applicable for bulk edits, but wrong!
‘cos each one is a form presenting old & new login plus button,
so you first have to find the one that’s wrong,
and in case of error, scroll down and find it again.

So that’s a very impractical, terrible UX. (WP-CLI to the rescue!)

However, aside from that, this plugin is the only out of three currently available plugins for changing usernames, which gets security and WordPress APIs right.

Recommendation: Rethink the UI from scratch. Integrate with the user edit page directly; e.g., via Ajax.
