The Catalog Pane pop-up that appears when you hover over a layer shows the file name, type, modified date and location. Could you add the Summary? That would be most helpful. If it would take up too much screen space, I don't need the Location. I'm in Catalog Pane. I'm looking at it! It would save time Viewing the Metadata.
Yes, that's where I was aiming for, but I see that I missed. Don't know if I can MOVE this, but will create a new post in Ideas and cancel or delete this one!
