I would like to suggest a couple of functions for the Prime RPN entry mode.
LIST→
The RPN Home entry mode has the →LIST function available when selecting a stack object, through the Stack menu. It collects the selected and underneath stack levels into a list. I find it useful to save into a list a set of numbers, unevaluated expressions or other objects to be used later (or other day). However I miss the complementary function, LIST→, so it would retrieve the elements of the selected list back to the stack.
SWAP at the right arrow of the directional pad
The SWAP operation is located at the right arrow in the HP48/49/50 calculator series: one single keystroke and the first and second stack levels are swapped. Other great machines have a specific x<>y key. So it could be a good idea to do the same in the Prime with this useful RPN function.
Cheers!
