I'm using the Exporter plugin and offering the ability to download a .csv file. The exporting of .xls doesn't require the classes below, but exporting .csv does.

Code:
		'Ext.util.CSV',
		'Ext.exporter.text.CSV',

Each time I add these classes manually, the JetBrains plugin removes them. I can get around this problem in this class if I uncheck "remove unused classes from the requires and uses arrays automatically", but this setting is very helpful 99% of the time.

Why does this remove these requires?
