Hi Tom,
I'd been testing in the Reality Plugin and not the Listings template. I installed the Listings template, and was still able to search on the home pages list section, but was unable to get the form to autocomplete when adding a listing. I checked the form and auto complete is set to on for the form, so I'm unsure why Chrome doesn't add data to it. It could be because it doesn't consider the fields to be personal data (e-mail address, name, etc).
Unfortunately there isn't really anything I can do to fix the problem. You could try searching the Chrome store for an auto complete plugin that will automatically fill a form with any data, or suggest to your client that they use FireFox or IE instead while using the CMS.
Thanks!
Greg
