Stefano,

That is a splendid idea.  In fact it is such a good idea that I have
been working hard for the past three weeks on exactly that.

Actually, my plan is a bit more ambitious.  Artemis will save *every*
fit you perform along with its log file and some other information
into the project.  Each fit will get its own entry in the list of data
and paths -- that means that you will be able to plot several fits
along with the data in order to see what effect each change has on the
quality of fit.  And since each log file is saved, you can do things
like generate reports on the log files to see how the R-factor,
chi-square, and guess parameters have evolved with every change in the
fitting model.

This is already available in a limited, buggy form in the new
development code in the latest source tarball.  I am hoping to
transition these features into the stable version by the end of the
year.  Something to look foward to...
