Page titles in PE currently show the ID associated with a particular entity (see screenshot). This is the same identifier found in the page URL.

1. Style these to be significantly more subtle.
2. Confirm these IDs are useful and should be shown. We'll start with the premise that "yes they are useful" and "yes they should be shown" - but if this premise is wrong, we can simply remove them or place them elsewhere in the view. (As noted, the ID is typically in the URL.)
