Hi Bob,
I guess I would have been surprised if a backdoor existed. Thanks for thinking
about this.

PNGJ is not designed to save any settings other than those that are
specifically necessary to define a state. So no user variables, no overall
preferences. You could save a "message" in the state by using the message
command, I suppose, but that would have to be a message that was visible to the
user. Oh, and perhaps in some relatively unused variable such as
set nmrpredictformat "testing messages here"
This would be human- or machine-readable in the state associated with the PNGJ
file if reopened by Jmol.
Although, come to think of it, I think I will remove that from the state. So
don't consider this method supported!

As far as I know user defined variables or functions (from jmolscript)
are not saved within the Jmol state.
The idea I have in the back of my mind is to use a file format Jmol understands
and have my data (your private state) piggybacking in that file. May be as a
comment in some file or in a jmol script file. Though I have not tried anything
yet.
I would welcome a solution supported by Jmol itself.

Apparently you can save blobs in localStorage [1]. YOu can of course also
save your private state in localStorage along side of the PNGJ but then you
do not have everything in a self-contained file.
