Automatically display the size and name of a file uploaded to Assets

Am using a file upload field, and was wondering if we can easily display the file name and file size using a field/file ID in template? There are more complex PHP approaches, but if Perch Assets knows them then surely we can call them yes?

As a note too, would be good to have the info seen in list view also on detail view of items in Asset library, as it's not in the default grid view. (File size, dimensions etc).

Thanks.
