Firstly, I apologize if my first email sounded too harsh to you.

It was not so much as Calculate is underdeveloped or not, I
think. (Almost every end-user software including Etoys is
underdeveloped). But looking at the similarity of Pippy and Calculate,
for example the plot feature you are making could be beneficial for
both, right? And, you would wish to have a calculator whose syntax is
closer to Python, right?

Yes. I filed a bug report for it. The length of old expressions
seems to be strongly affecting the performance.

Yes. I did it, too. It must be something to do with an error within
