Thanks. That would be useful. Ideally, where the directory and file structure of the functions should be a good categorization.

We have already tried to do the reverse, so that most common functions have a method version, like x.simplify(), x.expand(), x.factor(), etc. Aaron Meurer > > The app is in a development stage.
