2.6 included a lot of great updates for searching for ArcGIS Online items in ArcGIS Pro's catalog pane/view.

We have invested time into creating branded thumbnails and we actively use the Authoritative/Deprecated flag, but neither of these show up in the Catalog Pane's hover-over popup.
For example, even when sorting by relevancy, our authoritative road layer is buried amongst several other similarly named items, and you have to look at the "Owner" field to see if you're pulling the right one in:
Having the thumbnail and green check/red X in the hover-over would go a long way to visually identifying datasets with a quick glance.
