I agree with other recent reviewers. The screenshot shows a lot of fields, but none of them are enabled unless I "Unlock Advanced Settings" (which are in fact any settings) by providing my email. I know I could use a burner email for that, but meh, whatever. Cheers, bye.

Avoid: requires login to use

An add-on that requires your email to "unlock advanced settings" is never a good add-on.

An addon should not require my email address to do its job unless it's using a third-party relay, and an addon should not use a third party relay without indicating so in the first sentence of the description.

How am I to trust you with my e-mail address if you're either requesting it for no reason or implicitly lying about using a relay?
