I tried to use the the aggregation pipeline feature Export to Language, for PHP. The pipeline was quite complex, so I was surprised when I copied it into PHP Storm that the entire pipeline was on a single line, making it quite hard to read. PHP Storm will not add newlines for you when you request Code Reformatting, so the only way to make it readable was to add the newlines manually before reformatting, which is time confusing and error prone.

IMO it would be preferable if the pipeline was exported with appropriate use of newlines and indentation.
