The output files and fields can be modified from the program... go to the export area and select the PDF/Word option.
Here you can change sizes of fields, turn off headers and pages, add other words to disclaimers etc.
So you should be able to get a 'better' output more in line with what you want.
I also like the idea of 'calculation' files that might ask the 'components' of each equation and give an answer... or, allow a 'value' field and a 'calculation' field that allows access to do mathematical functions on values you specify.
And allow the 'smart field' to so something like a calculation (if X>10 then.....)
