[Plugin Category Shortcode] classes applied not default, not quoted

I noticed right away that this plugin does not use the default wordpress classes for cetegory styles. i.e. my category entries were largely unstyled or at least not styled as I would have expected them to be by default.

secondly, if you’re going to use default classnames that do not match whatever are the normal wordpress defaults for such situations, then an admin page allowing the admin to edit the styles for the classes provided would be in order.

and lastly many of the instances of the class names are unquoted in the generated html (which makes me seriously cringe)!
