Hey @brianbermingham. Thanks for reaching out. We don't currently sort Favorites to the top of the list from the Autofill prompt. However, we have an open issue to change this behavior, and I'll pass your request along to our team.

Thanks for the feedback, @Skilganon. I'll pass this on to our development team.
Thanks, @nancyT. I'll pass your request for this on to our development team as well.
