NSDockTilePlugin on Mac AppStore

I wanted to add some dock menu options for my application when it is not running. These dock menu options can be used to launch the application. I came across dock TilePlugin that can be used to add these dock options. But one of the comments in this forum discussion mentions that these Plugins are not allowed if you want ot publish your application in the appStore.

Can someone confirm this? If this is true, then Is there some other solution that can be used to add the dock options which appear when the application is not running, and can be used to launch the application?

Also do the recent open Files appear using this plugin mechanism?
