Stop auto-submitting forms in 1Password 8 on Mac?

Thanks Jack! Makes sense and its what I assumed based on my experience, I've just had my information inappropriately submitted to a newsletter sign up form on at least one occasion because the website likely uses the same form name or something for both their login and subscribe forms. Bad "form" on their part, likely, but I do feel like 1PW users shouldn't have to worry about their info inadvertently being submitted in the wrong place -- especially when that data could potentially be sensitive. I like the auto submit functionality in theory, if you can find a way to ensure under no circumstances, even bad website coding, will data be inadvertently submitted to the wrong form.

Thanks!
