In NSTK mode, it would look like the HP28/HP48 stack menu, additionally it had [4STK].
In 4STK mode, it only had [R^], [ROT], [OVER], [CLST], [PRST] and [NSTK]. (Or similar).
So you had the Stack commands immediately, the only (small) disadvantage would be: You had to press two keys to get [R^].

Hmm, interesting.

Personally, I approached the big stack primarily from a programming perspective. As long as you can program stackrobatics, I don't particularly care how hard it is to reach those functions. And the functions are all there: ROT = R↑N 3, OVER = RCL ST Y or PICK 2, etc.

But to meet these or similar requests, a custom skin could serve, for example, by mapping CATALOG → STK to the keyboard perhaps.

If cleared: After exiting all menus, it's like now.
if set: After exiting all menus, you are in the CUSTOM menu.
This would be a USER mode light.
(Alternatively you could switch [x<>] and [CUSTOM] keys ...).

A permanent CUSTOM option is already on my to-do list.

If you change into a directory and this label exists in this directory, it gets executed.
You could ASSIGN keys, set modes and flags.
You would need a flag to switch this behavior on and off (to get out of loops should it be necessary).

I'm not following, I'm afraid. Could you elaborate?

ad 1:
ROT and OVER were there to fill the 4STK menu only.
OVER and ROT are technically superfluous in the HP28/48 too, they are syntactical sugar.
In 4STK mode the general Roll and Pick functions are quite unnecessary.

ad 2:
Super. I will be still more happy with plus42.

ad 3:
It would be a simple way to set up an environment for special tasks.
E.g. for TVM problems you could automatically set FIX 2; for surveying tasks (at least in Germany) you could set up GRAD and maybe FIX 4, for BASE calculations you could ASSIGN shift and rotate keys and own programs to CUSTOM.
(I was a little bit inspired by .profile, .bashrc and .vimrc)
In HOME you could have your default environment.
It is a little bit like the states you can load and save, but the impact is much smaller.
