Halfway through your article and I 100% agree with all your complaints. I compulsively carry my T1-84 calculator everywhere since it feels like such an annoyance to have to resort to using any generic desktop calculator.

ETA: I am very impressed by your calculator so far. I thought my tmux + ipython setup was good, but this shows that I just didn't think about the possibilities of what a proper calculator app could bring to the table.

Thanks ! There were so many things to say that I was afraid nobody would read up to the end. GUI is only the visible part of the iceberg. Number representation (to keep exact values), accuracy, interval arithmetics... are hard to introduce in the first place.
