```Hi Carl,

Thanks for weighing in!

1. I’d love for Lilypond to be capable of respecting the desires of a composer
(e.g., Orff) in how it displays time signatures.

2. I’m pondering whether 1/6 is superior to 1 / [a single tuplet notehead]… I
bet if the preceeding measure had a bunch of triplets, the note-denom version
of 1/6 would be far easier to sight-read / process than the numeric 1/6.

I’m so glad you said this. This has been a vague rumbling feeling in the pit of
my stomach for the whole thread, and you finally put into words what’s been
bothering me about the whole thing!

Yes!

… which likely accounts for my naïvely optimistic hopes about how the feature
might be implemented.  =)

3/16 + 2/16 != 2/16 + 3/16   ;)0

I fear you’re correct… but I do love that I’m not the only one that hasn’t
totally given up the dream.

Cheers,
Kieren.
