Not sure what you mean here. RPN-67 SD saves the display mode automatically, except in vintage mode, of course. Additionally, in any mode, loading a program from a card sets up the calculator to whatever is appropriate for the program. This includes the display mode, the "trig mode" (deg, rad, grad) and the flags F0..F3. Just like the real HP-67.

Then I was using the Vintage mode only and had not noticed the display behavior in other modes, sorry! The updated version is fine, thanks!

If Vintage mode is meant to be as faithful as possible, perhaps you would like to know that X is not saved in last X for arguments equal to 0 or -1 for SIN⁻¹, COS⁻¹ and TAN⁻¹, according to the manual addendum (I don't have a real HP-67 to check this out). A minor trigonometric bug is also mentioned, but this should should better be ignored for ever.
