Aide Memoires
A player has a poor memory, and in order to compensate, puts any cards that are winners on one side of his hand, separated by a slightly larger gap.
Is this allowed?
I know that there are no rules specifying how a hand must be ordered, and also that if it was not allowed, enforcing that would be nigh on impossible. I'm interested in whether this falls foul of law 40B2(d).
I note with interest that although 40B2(d) appears under the heading of Partnership Understandings, is has a much wider scope.
Finally, I was expecting to find a note to the effect that the headings do not form part of the laws, but if it's there I can't find it.

Comments
I think the note about headings not forming part of the laws was removed in the 2017 Laws.
I don't think anything anyone does when sorting their hand would be considered to be an aid to their memory in the sense that it is prohibited.
If you call this a memory aide then surely sorting your hand into suits would also be a memory aide. Not a rabbit hole I'd care to go down. I think that since ordering your hand as you choose is specifically permitted, the general case about memory aides doesn't apply.
