Yes Paul, I agree with you!
Aodyo developers, what is your answer, please?

Re: How about a Sylphyo update now?

I agree, too!

Well, congratulations to your Anyma Phi 1.0 update. Really!
But now, finally got enough time and energy at your place to work on the long-desired Sylphyo update? ;-)

I think your fingering chart has some really good ideas in it.
Especially Rule 6: Raising the L1 for higher octaves would faciliate the work of the left thumb on the octave keys greatly (lifting/shifting). This should also work for the whistle fingering, or?
