Thanks for the suggestions, but I think I like the single text control better,
because I can imagine a lot of cases where you want the expression to transform
into the result so that you can use it for typing the next expression. If you
think about it, the history thing could actually be quite intuitive, because
you're used to it from so many other situations. So the chance is high you just
try the up arrow and voilá - there is your previous expression again!
Best regards,
-Stephan
