Subject: Re: Work on Basic Mathematica Stephen!

All,

Count me as one who has been using Mathematica since Version 1, and who uses Mathematica for serious Mathematics and for teaching. Mathematica enables me to do things expeditiously that would take a tremendous amount of effort to do otherwise. So I love Mathematica. I wish I'd had it when I was in college.

Having said that, I agree with many of David Park's comments, especially about the Front End and stability. I would like to see Wolfram Research pay attention to David's constructive criticisms.

Adding my bit to David's comments about Front End stability, I'm one who complained about the new default notebook style that surfaced in Mathematica 9. The fonts and text color used in the new default style are ugly. Moreover, opening an old Mathematica 8 default notebook in Mathematica 9 changed all the fonts and colors to the new undesirable ones. I complained to Wolfram (apparently I was not alone) and a workaround was found by including the Mathematica 8 version notebook as a style that one has to select (as opposed to the default style). So Wolfram was responsive, but the lack of foresight remains: Why not reverse roles and include the new default notebook style as an option and keep the old one as default? This would address one aspect of stability that David eloquently describes.

So yes, Wolfram, please pay attention to Mathematica and the effect changes on users, particularly the stability issue. Change is good, but it has to be done well.
