I have found out that I often would like to see a larger preview image of a stamp or texture in the Asset Catalog. Sometimes it's hard to see details or differentiate similar assets (especially textures) from the tumbnails.

I know it is possible to open an asset into a new tab in the Art Manager, but not in the Asset Catalog. It would be great if you could preview the asset in larger size by right-clicking it or clicking a magnifier glass icon, for example.
