Hi,
I have a question regarding Activity Chaining?
Activity Chaining is useful only for User input task to show synchronosly or any other reason?

IMO, activity chaining should be used for either API requests or interfaces.
For APIs, it's mostly because you might need a certain amount of nodes to complete to be able to return values to the person calling the API.
On interfaces, you usually chain database writes to ensure that when you refresh the screen, the values are displayed.
Chaining is also useful for on-interface calls of a!startProcess() if you need to get the data resulting from any part of the process to pass back onto your form.
