Hey!
Such a powerful tool! Congratulation PlantTeam!
In this case I would like to have the endif diamond on the B column and not in the A.
@startuml test
|A|
if (A?) then (yes)
else (no)
|B|
: B home;
|B|
endif
: staying in B;
@enduml
The easy way should be to use the column over the endif statement to select the column in which displaying the diamond.
