Thanks for the report; it's good to get more things fixed for
the 1.8.2 release.

Fixed (along with a few other cases where conditional enabling
of GUI controls was not right).

Not fixed.

We'll try forcing non-use of errorbars for T > 160.

Fixed (the temporary GMM weights matrix was being exposed by

Point taken, but not fixed yet.

I've now made this output more compact (under most conditions).

They are now marked.

Now marked.

No (portability).

Yes, it's possible.  But I don't have time to do everything that
is possible ;-)

I think this should be fixed now.

Yes, thanks!
