Re: Shift up OttavaBracket

That’s because neither 2 nor 0 is large enough to be outside the items in your 
example (e.g., the noteheads are at +4, and the slur is at an even more distant 
position). In my example, I used 10, and it did exactly what I wanted: placed 
both OttavaBracket objects 10 spaces away from the staff.

Not in my example: I know its reference point is exactly 10 spaces from the 
reference point of the staff.  ;)

No… extra-offset shows how you can move an object from its calculated position, 
but not "the correct behaviour" (i.e., what you want) in that it doesn’t push 
anything else around. Right?

The difference between 2.18 and 2.19 shouldn’t even be a talking point — 
they’re different versions of the software.

I’m not sure how to do that technically… and to be honest, to me that sounds 
undesirable (at the very least from a performance perspective).

I hope someone else is able to answer your question(s) satisfactorily!

Best,
Kieren.
