Yeah, the goal of the project is very similar to Formula Pro. Pages are organized by topic, and on one page you have textbook formulas for showing your work. On the next page you have the "cheat sheet" of formulas in calculator-input form, which you copy and paste, then change the variables. What it does is show the student what formula is needed by topic being covered in class. The interface is much easier to remember than scrolling through menus.
For the screenshot on that page with n=, if you know your problem is about finding the sample size needed to achieve a margin of error, you'd know to go to the page with n=. Then if you were doing it for a proportion, you'd use the second formula. It saves you a ton of button pushing.
I think I might release two versions in the .zip file, one where the formula pages are organized for someone at the end of a typical intro statistics course and one for a student at the end of it.
