That's really nice, Willy. That would work, and if you could display Y, Z and T as smaller red LEDs, I think I’d faint!. Some haptic feedback on the keys to simulate that amazing key-press feel that the HP 3X series had would be most welcome, as would a full-screen mode, like Antonio Lagana's 'Classic' skin for his HP 41CX...

I think in the end it will look like in the picture below. You dismiss the stack by tapping it or by swiping the display left. You call it up by swiping the display right. Quite convenient, actually. Implemented in RPN-32, -34 and -38. Thanks for the prodding... ;-)
