There are at least these issues with this:

1. There is no "file layout" button  and therefore know exactly which columns are required

2. Because of reason 1, we have to rely on the 'sample file'.   It is 19 columns wide!  Surely all those are not needed

and

3. We cannot view previously loaded files as with [nearly] all other imports, so we cannot see what we have successfully used in the past. 

Why doesn't this work like all other imports?
