Well some of what you mentioned has been implemented in array languages and some like superscript and sub script was part of the original apl book (the book on the notation pre the implentation). Its somewhat ironic, orignally apl was supposed to make math notation more readable (it was originally just a math notation) but many people dont see it that way. if you are interested in super scripts and the like you might check out bqn and uiua which both are doing interesting things with the symbols. although uiua in particular suffers from having to choose from a set of symbols that comes from unicode and therefore sometimes look a little off to me

Is this the book? https://www.softwarepreservation.org/projects/apl/Books/APRO...
I wish APL derivatives embraced some of these ideas, and made their magic spells easier to parse visually, and to format for readability. I don't know how to achieve that easily. Mathematical notation took centuries to develop. It took quarter of a century for programming languages to normalize indentation. Maybe APLesque languages will eventually come up with a notation that's less impenetrable than APL / K / Q, but less verbose than Pandas.
