I know, but in July-August I'm in holyday, so I will have a lot of spare time 
to dedicate
to this project.

Actually we use it at the university of Trieste (Italy) in the analitical 
chemistry lab,
the class of Dr. Gabriele Balducci that developed this software many years 
ago.
Now I rewrote the code in a more modern way.

It is not necessary to share data, because this program is useful only to know 
the solution
of a analitical question or seeing results of an experimental titration. They 
will
share these data simply because students must write a report for the teacher.
Icee make easier many calculations, expecially for the "best fit" algorithm
to find out the equivalence point of a titration. These calculations could be 
done
also with a hand calculator, but it would take hours: Icee does all 
automatically.

>is it possible to use an existing free format (making sharing data easier)
Probably a ods file could be used in a strange way to save Icee project file, 
but this
doesn't have any sense: there are no other programs doing what Icee does, so
also if we use another format for project files, there will be no other 
program to 
use them rather than Icee.

I know, I would like to integrate the KmPlot plot widget. Obiously the plot 
doesn't
have a real utility: the lab reports, in fact, need only the result given in 
"Note". 
Anyway i found that for many students the presence of a plot is useful to 
coprehend
the chemical dynamics of a system, so I wrote that simple widget with  QImage.
This is a thing I really want to improve, but I released it as it is because 
actually we
are finishing lessons and students needs Icee to prepare lab reports.

Thank you for the questions.
