My dream DM42 display layout

I love the vintage HP font (shift F5) and that it is in different sizes too, but the optimal for me would be more like the beta version had it with the lower area using a large easy-to-read font, whereas the other registers had smaller font. Also, the "status line" is better placed here, IMO. There is still space for a permanent menu at the bottom as shown. Additional modifications:
  • Less dominant register letters and colons (actually original HP42S)
  • Less dominant down/up arrows
  • Non-rounded function menu buttons with more spacing. Looks better to me.
Finally, an idea is to have the last function executed to be displayed on the "status line" area, e.g. E^X as shown (should disappear when another button is pressed). BMP file:

Too busy for me. But thanks for taking the time to provide a sample screen image, it would have been difficult to visualize this from a description.

Who needs Z, T, and L displayed as long as he knows they are treated properly??

Well, it's super useful to see the whole stack when debugging a program, at least for me.

Thanks for the feedback, however I am a little baffled by the answers because most of you are actually critizing the very reason for having a larger screen to begin with. In fact, my attempt was to make the screen less busy by focusing on the important stuff (x and y regs), while still providing useful information in a separate area. Everything else than the X and Y registers are secondary info on the screen (but still very useful) and should be kept small to minimize noise. A further step would be to make the font in the soft menu key smaller (need not be much larger than text on the physical keys).

Now, the vintage HP font is not for everyone, and I would actually love a nice modern font, but the current standard font is not quite there, unfortunately. And finally, the upper area would not need to show the stack top registers at all (just as currently), but it is a lost opportunity and a waste to leave it completely unused.

/Edit: To be clear, I fully respect that it is useful to remove all other information than X, Y when doing normal calculations, and that is indeed the least noisy display. My post was more an attempt to show how one gracefully could display additional info (when you need it) without cluttering the display.

I would just like to see the stack aligned to the top, not the bottom. Every time I open and close the soft menu it makes the stack jump up and down. The original HP-42S did not move the stack for screen space. I'm a fan of seeing all the stack (and L).

+1 from me.

It emphasizes the X and Y registers nicely while keeping the others in plain sight which I also like. Slightly busy, perhaps something to do with vertical alignment?

@jfb9301, yes I also think the stack should be aligned to the top, or actually just stay statically the way the image shows when soft key menu is closed. E.g., if you only want to show X, Y, L, the separator line and X, Y stays fixed. That way, the display becomes even less busy with plenty of space above and below the X, Y registers, making it natural to focus on them.

Here is a more typical scenario when the menu is closed and showing the Z and L regs. Still too busy?
