He asked me that am i talking about installed plugins? He was asking right i was talking about installed plugins but i wasn’t able to explain the feature so i tried to explain him again that just like drag and drop page or post order i’m referring to drag and drop plugin on plugins page.
He informed me that by installed plugins means plugins page. He assured me that he will work on this feature. I thanked him. And he informed me that the feature is added in WP Sort Order version 1.1.3.
