to Apple Menu is a script droplet to add items to Apple Menu Items in the active system folder.
Launch to Apple Menu directly to open the Apple Menu Items folder. Drag and Drop items onto to Apple Menu to place aliases of them into the Apple Menu Items folder.
This script requires the scripting additions File Commands, Display Dialog, and String Commands in addition to the Finder Scripting Extension.
It's looks a bit desheveled (after several patches to add functionality), but it has performed well for me.
