[Ifeffit] Some thoughts on gifeffit

[Dr. Paul Fons]

  I just brought up gifeffit this morning -- and I can already say I like 
it.  I was wondering about some simple changes (perhaps I can do some of 
these myself once I get a little more sophisticated)

1. It would be nice to have legends on the pgplot window -- colors are 
nice but if one is comparing different data sets, it is really hard to 
tell them apart (especially if the page is printed).  Also one of the 
things I used to do with the unix environment was to set up a series of 
different autobak files with different rback settings so I could see the 
effect of moving the fit window.  It was nice to be able to compare all 
of these in the same graphic window -- it doesn't seem like this can be 
done anymore (am I right about this?)

2. In terms of documentation, a nice intro would be to highlight the 
differences between gifeffit and the more traditional unix command line 
version to help new users get up to speed -- again I am willing to write 
some of this (if help is needed), but I still need to get up to speed 
myself!

3. I am not 100% sure of this, but it seemed that when, for example, I 
had the plotter open and subsequently read in a new data set in another 
window or defined a new array, the pop-up menus in the plotter window 
weren't aware of the new data set (at least not immediately).

One last thing, on the ifeffit homepage, it is stated that feffit is 
included in the distribution, but is not stable -- what is unstable and 
what are the limitations of the feffit module within gifeffit currently, 
e.g. is it something I can use to fit data?

Last thing -- but really should have been first.  Thank you for putting 
all of this effort into ifeffit and then sharing it with the rest of the 
community.  Many people are benefiting from your efforts.  Bruce's 
course (which is still a developing entity I believe) is also of great 
help in learning more about the different approaches to data analysis.  
It is my impression that while there is a fairly good collection of 
knowledge regarding exafs (and less so for xanes), this information is 
scattered in many different locations (and some of it is very dated).  
Having a reference in a easy-to-find place is a real benefit to the 
community at large.  It also would have the advantage of being dynamic 
in that it doesn't have the birth (and death) cycles of commercially 
published material. I guess all of this is obvious, but I just wanted to 
say thanks (again).
