When configuring a 2d instrument, there is a concept of property
aliases. The README.xmlpanel example uses absolute property paths, but
the real world instruments I've seen use relative paths with a lot of
../../../../../params/etc.

I've received a complaint that thermals in 0.98 are not working. I don't
have
0.98 on my system but I tried them in the CVS version and see that they
are
not working. I'm guessing some changes were made in the AI subsystem that
killed the thermals.
Does anyone out there

That should be just an y instead of true:
B trace-read=y456/B
and this is how you get a report

With proper indentation you just count the tabs in the alias line.
