I'd love to see the ability to insert images/icons/favicons into a field (possibly the embed field) in an Asset layout so I can have a quick visual indetification of a field via it's logo. Example use case for this would be putting the application logo in the very first field of the Application asset layout so you can see straight away if the client has XYZ. Inserting a simple image file and having it appear in the table view is all I'd need but the abilitly to add gifs or other dynamic content here would be really handy.
