This would be a very helpful feature. Screen space is at a premium, and some of our collection names can be long as we use the term Young Adult Fiction.

A related customization feature for call number/collection: Requesting the options to display the collection code and call number for the record (Always show, only when copies are available, never show, etc).
At this time, the listings with no copies available don't show the call number or collection in the at-a-glance.
"Find a Copy" only shows call number.
Clicking on location will show the item level collection.
Scenario: Our Book Club Kits (bags) are TOM as Kits (nearest available option for consistency across Polaris Leap, PowerPAC and Vega), along with many other records that are also Kits (thus not conducive to renaming in Vega). Without prominently displaying the collection, the Vega patron may misinterpret this listing if they don't click on a specific location.
