I'm adding two more trackers for this. What is needed is the ability to search and to sort based on the file name value inside the "File Download" field which is of file data type.
In the absence of such features, as shown below, I have to include a Text field to store the file name. This allows entries to be retrieved and sorted by "Document Name".
Hopefully with these 2 features in place, we will help move the Dataform plugin to "Infinity and Beyond".
