That was it. Now I understand what it's doing! :o

Hi Brian, the Flip command does actually get installed by default with the app, it is not a plug-in that needs to be installed separately. But because there is no icon set up for it yet to actually trigger it you have to set up a keyboard shortcut or type in the command name.

In v3 I am hoping to have some UI set up that will hold a menu of additional commands for stuff like this.
