            Bug ID: 459708
           Summary: "Shift" functionality hidden, misleading, and wrong.
                    Expose all buttons by default. Or expose the fact
                    "secondary" features MAY exist. You don't now.

SUMMARY
***
There are no less than 5 diffrerent bug reports of people not being able to
find a square root key. This is MY report of BAD UX because this should not
over the course of the products lifetime contribute to ANY bug reports of a
missing square root key.

STEPS TO REPRODUCE
1. Open kcalc
2. switch to scientific mode
3. expect to see all the useful operations, and not have them be hidden behind
an ambiguous "shift" button. 

OBSERVED RESULT
12 buttons change. The entire left column, and M+ now becomes M-


EXPECTED RESULT
SHOW ALL THE USEFUL FUNCTIONS AND NOT BEHIND A "SHIFT" BUTTON WHICH IS
AMBIGUOUS AND DOES NOT EXPLAIN "EXTRA FEATURES" "EXTRA BUTTON FUNCTIONS" etc.
its JUST SHIFT.

Why do I need shift? I never have used shift on a calculator before.

I've seen "2nd function" on a calculator. "2nd" not "SHIFT".
Rename the button "2nd function" to imply there may be something "behind" the
visible but not useful to me (trying to find sqrt) buttons present by default.

ADD some sort of "extra text" 'around' the buttons, to imply a secondary
feature, like Texas Instruments does:
https://education.ti.com/en/products/calculators/scientific-calculators/ti-36x-pro
Notice how every button with a "2nd function" has BLUE TEXT above it, and THE
2ND FUNCTION BUTTON IS BLUE TOO.

THIS is an example of GOOD, INTUITIVE, AND HONESTLY IN 2022 THE EXPECTED WAY UX
ON A CALCULATOR SHOULD BE.

NOT a button that "can't be found"(missing sqrt by default)
NOT a word (shift) that "means very little, and borderline does not mean what
it does unless the context of 'buttons can do something else' is enumerated at
ANY point, which it ISN'T".






SOFTWARE/OS VERSIONS
This has been a problem since 2004 apparently. It does not matter what version
im using, since all bugs to closed as "not a bug/wontfix" so no fixes have ever
been committed.
But for what its worth, 
Ubuntu 22.04 
Plasma 5.24.6
Frameworks 5.95.0
