HP Prime suggestion to avoid Numeric/Symbolic confusion Message #1 Posted by Chris Pem10 on 18 Nov 2013, 7:24 p.m. I'm done ranting and ready to help :) Let's use the great color screen to our ADVANTAGE: ANYTHING RELATING TO NUMERIC COMPUTATION IS DISPLAYED IN BLACK. Grant me a full upper/lower case alphabet for numeric variables... just color them BLACK. ANYTHING RELATING TO SYMBOLIC COMPUTATION IS DISPLAYED IN BLUE. Grant me a full upper/lower case alphabet for symbolic variables... just color them BLUE. If a variable is UNDEFINED, make it ITALICIZED. If a variable is DEFINED, make it BOLD. If an input field accepts numeric values... frame in in BLACK. ... BLUE frame for symbolic... Units in BROWN... so I can have m_m^2 if I so desire (variable "m" meters squared). Reserved system variables in RED. Just a suggestion.

Make the colors user-selectable (from more than a measly few -- theme color selection, I'm pointing at you).

I support that 100%. But i have another radical suggestion: Scrap the Home-View! After working a few weeks i never used the numerical Home-View! If i need numeric results i press Shift-Enter. So the numerical view is included in the CAS.
