Grob type (and other metadata) in point-and-click url

[Bertalan Fodor (LilyPondTool)]

Would it be theoretically possible to include other metadata in the 
point-and-click url besides the input file position?
I'm looking at:

(define (grob-cause offset grob

I'm not sure, how much information is included in that grob object.

If a text script for example would have the information that it is a 
Voice.TextScript, or that the notehead it is coming from a note event it 
would allow powerful finishing tools, like extra-offset, adding 
transposition in the editors.

What do you think?

Thanks,

Bert
