Hi,
I believe the following three lines are currently not supported by Dorico:
The first two lines are not so time-exposed, but the one on the right is not so efficient to draw:
Could they be implemented in a future version of Dorico?
Thanks in advance!
Arrows are provided in the Lines panel in Write mode, and you can create your own variations using the Library > Lines dialog. The angled line you show in your picture is not possible to create in Dorico as a single line at the moment, but you can get something approximating it if you create a start line annotation of an outward pointing hook, and an end annotation of a downward-pointing arrow. When you then rotate that line through 90 degrees, it will look something like what you’re after.
