After applying the modification suggested by @bjorkert, commit aa9252e, this PR is a definite improvement.

Once the password icon is triggered to show up, the cursor can be on either the URL line or the token line and both URL and token are updated from the selection of a saved password.

Note - the saved passwords have the NS URL as the username and the token as the password. I have a series of these passwords I use to test all the types of URLs (Trio, Loop, Loop with no treatments) when testing LoopFollow updates.
