Re: how close are we to having an "addAt" or "insertAt" feature?

Hi Jan-Peter (et al.),

Your edition engraver is amazing, IMO.

Here is page 1 of the Vocal Book for my musical “Fairy Tale Ending”:

Description: Adobe PDF document

There are ten tweaks on this page. (Yes, there ultimately need to be a few 
more… but it’s a testament to how awesome Lilypond is that it looks like this 
with only ten small manual adjustments!)

Leveraging the edition engraver, I have removed those tweaks from the content — 
where they were embedded using a frustratingly complex system of tags — and put 
them in the presentation file where they belong; the presentation files for the 
other five standard outputs (i.e., Full Score, Piano/Conductor Score, Piano 
Part, Percussion Part, and Bass Part) will, of course, have their own set of 
tweaks.

Finally, a way to truly separate content from presentation.
Thank you, Jan-Peter — you have provided me with the biggest improvement in my 
Lilypond workchain since perhaps my very first download of Lilypond.  =)

Cheers,
Kieren.
