I have now added proper display of clues for 1-letter words (i.e. none), and included a boilerplate README file.
The biggest new thing, however, is a fully-functional (and hopefully user-friendly enough) crossword puzzle editor to make your own crossword puzzles! It is written in Python 3, so have that installed to run it. Hopefully everything you need should be included. There's a new puzzle now, too, and it's today's mini crossword on the New York Times website!
