I tried importing a number of files in a single drag and drop - selecting several in file manager, and dragging them all in at one go. This seemed to work well but created a couple of moments of doubt.
One or two of the files had relatively little data and had not sufficient to enable identification of the date format. The import process asked for confirmation of the format in use - but it didn't tell me which file it was importing. In my case all files used the same format (and I suspect that this is the normal case) but it would be comforting for the file identity to be included in the request for format confirmation.
In a similar vein - when an import file name does not match an existing account the process asks if this date is to be loaded into a new account or an existing one. Here again the request does not identify the QIF to which it refers. With careful file naming this was not a problem - always a new account as the QIF was unique to an account - but it would be helpful for confirmation of the file identity.
