Hello,
in an activity diagram, I tried to change the thickness of borders for notes using skinparam, but the thickness remains unchanged. I could change the color of the border successfully.
Plantuml version used : 1.2018.09
@startuml
skinparam NoteBorderThickness 10
skinparam NoteBorderColor green
start
-> Test 1;
:Test 2;
note right: Hello Note
-> Test 4;
:**Test 5;
stop
@enduml
Thanks a lot
