Yes, also important is the ability to add action classes from plug-ins=20
later.
This will be the real tricky thing I think.

I did not doubt it would be possible.
Initially we have to create three frames and add the different panes=20
depending on which view is chosen (one or three windows) depending on a=20
default or user preference.  A preference listener keeps track of this=20
preference.  If it is changed the appropriate method is called and panes=20
are added and removed from the appropriate frames.  I don't think it is=20
more difficult than that.

Hmm. Maybe.
