hello
Is require a new function menu to re-execute the history and not have to edit expression by expression (line by line) this feature is available in the CASIO classPAD serie 300/400 calculators
I do not want a clone of the CASIO calculator, if not to equalize technologies
is very important for example, to compare outputs between different modes (maximum simplification and none simplification).
///////////////
another application
if you want to change a parameter, easily edit a x-line and all the history changes down, is like an interactive history (classPAD300/400)
