EDIT: NEVER MIND THIS QUESTION.
I found this menu when right-clicking programs from the 'All Apps' menu from the top/right of the Start11 page.

I just bought Start11 a few days ago, and have been customizing the menu.
At one point I was able to right-click a group of icons and there was an option to Pin to Start11 'Tab'. And a list of the tabs was displayed in the menu to pick from.
But I cannot for the life of me remember where that was, or how I got that menu?...
Does anyone know where that is, or how to do that? ??
