Seems like there should be a way to control the horizontal position of duration. In the example below the text is overlapping rendering the duration functionality pointless
@startuml
!pragma teoz true
{t1} Bob -> Alice:
rnote over Alice: Some note
{t2} Alice -> Wall:
{t1} <-> {t2}: Duration
@endml
It would be helpful if it was possible to define the horizontal position of the "{t1} <-> {t2}: Duration" and even place it before the first and after last participant
