This is a very useful tool once you figure out how to use it, but for one critical aspect - the plugin works with European formatted CVS files, not US formatted ones. Comma-delimited files don't seem to work. The delimiting relies on semi-colons. I can maybe figure out how to make a conversion, but it's not suitable for clients. On a large file, doing a search and replace for commas isn't feasible, as some commas have to remain commas.
Conceptually, though, this plugin is great. Just point it at a csv file and off it goes. Deserves broader development and documentation.
