Request for suggestions: algebraic equations in Free42

[Logan]

Thomas,

This would be wonderful! Editing equations in RPN steps is a bit obscure at times so I really enjoyed the equation editor on both the 32s II and the 35s. I demonstrate them in these videos:

For something on Free42, I could envision an "equation editor menu" which would give you quick access to parentheses, and left and right arrows for editing a specific location in the equation.
