Essential Widgets: Categories

Your widget description says: EW: Categories: Essential Widgets Pro supports Categories widget. The widget provides you with various customizable options such as the title of the widget, taxonomy option, order option, number of categories to show, display as a list or none, number of posts to display, sort by option, select feed type ton display and display as text or image. Although, even for me, most of those options are self-explanatory - for the life of me, I cannot make them work. Is there an instruction sheet for what they are supposed to do? Thank you. Bruce
