Most login forms nowadays have the 'Remember me' checkbox that keeps you logged in for 30 days or whatever. On general security principle, I find it's better to not check them when I save logins in 1Password. However, sometimes I'd like to have the form remember me, but it's a pain to do so because autofilling unchecks the box and then autosubmits. The only solution, as far as I can tell, is to disable autosubmit, then autofill the form, then manually check the box, submit, then re-enable autosubmit. A better solution would be for autofill to not change the current setting of the 'Remember me' box, so you can just check it first and then autofill+autosubmit. I imagine this could be done either by allowing particular form elements to be ignored by the autofill, or by just adding specific logic for the 'remember me' box.
