Looks great. I can't try it right now, but looking at the documentation I would suggest an alternative to CSV upload.
For larger documents CSV can be annoying. The line breaks needs to be escaped and commas need to be escaped. Pointing the application to a folder containing a corpus of text files is much easier.
