There is one possibility for improvement. I do not know if this app provides this but txt files are often line oriented with a CR/LF at the end of each line while ePub is paragraph oriented with all of the lines fitted to the width of the screen. Some conversion applications can ignore CR/LF sequences and depend either on a blank line between paragraphs or an indent of the first line in a new paragraph. If this app can do this it can turn a text file into a readable document for eBook readers.
There are also some coded conventions used by Project Gutenberg to encode italics, bold, breaks in txt etc. into a txt file. If this converter can recognize those conventions it can also be useful in converting books.
