I believe it would be very useful to be able to see the file name of the uploaded CSV file in the web view of refrence data and images. Quite often when developing Apps you name your reference file something else to what you called the CSV file. Then when it comes to updating the reference data you have to download the file edit it and uploaded it again where as with the file name in the web viewer page you could cut out one step. Also if other develop apps you have no idea what they called their CSV file.
A good work around as suggested to me by Support was to include the CSV file name in the description. But this requires a degree of discipline many us don't have
