Since there is no "step-through" debugging available in service/subscription script editor, developers have to rely on writing debug log messages into their code. Unfortunately, reading the log entries is only possible in another view, Monitoring>Script Log. As a result, users have to switch the views a lot, constantly reloading them, or start to use multiple windows. This should be easier.
I suggest to either make the script log view "detachable" to have it as a floating window in the script editor, or (a bit simpler) provide the script editor with another in-view way to see the written log entries, e.g. a collapsible section at the bottom.
