What would you like to see in a future HP Prime II? (HP Prime², HP Prime 2X)

[CyberAngel]

New Prime?
Is it feasible to have a HP-28S or HP-18/19 Business -like wallet calculator?
When doing any calculator key (button) manipulation
the extra keys on the left side could be assigned as complex numbers using the imaginary part as the new key_id.
ISKEYDOWN(key_id); GETKET, ...
I mean if pressing [ 1 ] returns 42 then on left side [ Z ] could return (0, 42)
OR use negative numbers for the left OR alphabet stringsm
hmmm...
ISKEYDOWNALPHA(key_id); GETKETALPHA, ... would get the key name!
Exactly as written on a key, eg. "SIN"
Programming as usual:
KEY K_A...Z, LC, ENTER, SHIFT or whatever HP 28S had on the left. side of the calculator.
