You mentioned a calculator - and I do remember a march months challenge (in 2021) by @Jeff_Hager where I worked quite a few hours creating a calculator.
Using the new component with the following prompt
create an old fashion calculator. Make the buttons work so
input can be given on the calculator. clicking the result
button must show the result of the calculation the
calculator should fill the whole screen
gives a calculator app like below - and it works.
This beyond belief
