To have a default paradigm open at startup, simply name a paradigm "default". Text files can be converted simply by dropping them on the application's icon in the Finder. If there is a paradigm named "batch", dragging text file icons to Paradigma will start a batch process, where the program will proccess the files automatically, then close down.
Use "Make ParaDoid" from the File menu to create a noninteractive standalone application with the current paradigm, in batch mode.
The new popup menus "Repeat" and "Next paradigm" in the main window allow automatic chaining and repeating of paradigm conversions on the same data file. The user can specify a series of paradigms to be run in sequence, and how many times each paradigm will be repeated.
