Rocky,
It's stand alone and it's small, fast and efficient. I have 3 MPN files that I maintain with it. With it you can.....rearange & organize folders and patterns, rename them, delete them, back up you pattern file and more.
Simply a great program that I wouldn't be without. It's what Designer "should" do for us.
I had the multiple Favorites and such too...lol...Not any more.
One thing, you cannot access the "basic" folder as that's a proprietary LHR file. It's a good thing too because there's no chance to mess up the patterns that come with Designer......
