Hide unused participants in sequence diagrams

Question

Hi

Is there a way to hide unused participans in sequence diagram ?

Example:

participant A
participant B
participant C

A--> B: hallo

In above example I don't want empty C block in  the sequence diagram.

It's note very documented, but you can have:

@startuml
hide unlinked
participant Alice
participant Bob
participant Other
Alice -> Bob : hello
@enduml

Is this what you are looking for ?

Can I focus view on several Participant and hide others ?
It takes us easily for certian participant to check thery own sequence and messages.
