brackets, arrows, ...

How do people insert brackets (straight and angled), arrows etc.?
I’m working on a collection of short music examples for a edition of Schoenberg texts, and tried inserting SVGs as graphic frames. It works, but fine tuning size etc. changes line widths etc. if using “fill” frame mode. Of course this is to be expected, but maybe there are better solutions?

EDIT: Ok, just found the tuplet trick. One ticked … arrows?

PS: Dorico Pro 2 is a dream come true …!

A solution for horizontal brackets has been given there, thanks to n:n tuplets.
For arrows, you can use a closed hairpin () and insert an arrow head as text.
Not ideal, still workarounds…

Closed hairpin … neat trick!
Thanks!
