It would be very useful if one would be able to add a note to a ticket which was procesed by a scheduler task.
As the docs mention, that the Note field on the scheduler doesonly add a note/descriotion to the task and note to the processed ticket, I guess the zammad team generelly sees the need of such a feature.
We use the scheduler to set the state of tickets who reached the pending time back to open.
With no note that the pending time has been reached, this confuses agents as they do not see clearly, why the ticket is open again.
