The program pointer of this calculator stays at step 000 always, hence BEG is lit Remember the WP 31S is a subset of the WP 34S.

There are some aspects in your layouts I definitivly like. ENTER with FILL and x<>y with x<>, for example. (BTW, I think quality of layout suggestions has risen over the years. This seems to be a learning forum after all. Kudos to Karl Schneider who opened my eyes for the beauty of well thought layouts years ago. Does anybody know what he's doing now? I didn't read anything from him for many moons.)

Some remarks in random order, reflecting my point of view only, of course:

• I wouldn't put STO and RCL in top row - and I don't see a reason for doing that.
• Putting DEG and RAD in a row with SIN etc. has some charm. OTOH, they are far away from -> then ...
• I didn't observe anybody writing LOG₁₀ for the decadic logarithm in real life so far. Admittedly LG looks a bit weird (like LN does) but I didn't want to frighten our American friends with the official lg and ln - I've learned they prefer capitals.
• After all, the label CONST is the longest secondary label we have. One reason for putting it on ENTER.
• With FILL and x<> in the ENTER row (which I like as mentioned), two catalogs must be put elsewhere. CONST can't go anywhere else in the top three rows for plain space reasons. So it has to go down. But why put it right of -> although -> doesn't interact with CONST?
• Colors were discussed elsewhere already.
  

At the bottom line, the WP 31S layout (as any other one) is a "Gesamtkunstwerk" wherein everything has to fit nicely - well, as nicely as possible. I'd recommend thinking about function grouping.
