So this goes both ways, does it? I mean that also a new console/script
estimate does not affect the model which is used for menu commands?

I can see the point, although personally I use (or would like to use)
gretl differently. The behavior should probably not be changed unless
there's a better reason than my personal preference, but maybe should be
mentioned in the documentation. Btw, is there a kind of system to track
enhancement requests like these? I might get around sometime to
contribute some documentation, but not right now. And without a
bugtracker this may be forgotten.

Right. Anyway, I guess my stumbling point was just the fact that
matrices aren't yet supported via the gui. It would be nice if that
could be added, but I understand/agree that that doesn't have a high
priority.

Thanks,
