We will take into account your suggestion.
About your problem, it is just enough to set "Choose source type" parameter to "CSV" and enter path to a CSV file in "CSV -> Path to CSV file" parameter. If something doesn't work, it can be a problem if an incorrect path to CSV file is entered or a javascript script conflict with a 3rd party extension. We can investigate the problem in more details if you provide a link to a page where you try to use the extension and send screenshot(s) of module settings page by
email.
