I know that these wishes have been mentioned before, but I just finished an Smath worksheet and submitted it to my boss for his review. This is the first time I have actually used an Smath worksheet in publishing calculations for the perusal of others. In looking over the finished result, I am reminded how these improvements will be absolutely necessary to produce more readable worksheets:

1. Literal subscripts: This one improvement would improve the readability of calculations more than anything else.
2. Font control: the ability to control the choice of font and other settings such as bold, italics, underline, etc.
3. Plot control: the control of line/point color, boldness, etc; the ability to control axis range, graduation increments,etc.

These improvements are in line with the idea that one of Smath's greatest strengths will be its ability to present calculations in an easy-to-read format that anyone with technical training could understand within a short amount of time.
