AREXX support is minimal. MUI provides some AREXX control, but I haven't yet set up support for more complex actions, or documentation of the AREXX support that MUI already provides.
The ini and inc lists in the GUI do NOT currently save their contents with the default settings.
This is being fixed, and the new version should be available at the POV-Amiga support page soon.
