As a math teacher I want to add a point to the wish list:
At the moment the calculator puts numbers at the edges of the plotting window indicating the maximum and the minumum values - I would prefer to bind the numbers to the last tick mark on the axis. Reading off the values would be simplified. For more precise values one can go with the Trace feature. But students should learn to read a graph without the help of a cursor! Perhaps one could make the feature switchable (a flag)?

Sorry for the off topic question but can I ask you the age of your students?
