JOC: the task and order log is shown when you click on the history entry or you use the context menu. The button 'show log' is removed.

You see the order history or the task history on the right side when you choose a job chain or a job on the left side.
In this history the button 'show log' is removed. Instead of it you can click the history entry directly to show the log.
In additional you have a context menu to show the log.
