^^ Good review of Ultimate Favs...
Just a suggestion. If the "carousel" display isn't crucial for you, "Folder Organizer" provides the same functionality with a user-selected icon opening a "panel" of associated apps. It has some of the organizing features (such as ordering of the apps in the panel) that Ultimate Favs apparently lacks.
It used to be called ABCorganizer and is available in a free and paid version in the Market. The two are identical except that the free version has ads in the setup screen. (Not in the app itself.)
As the apps spin in a circle I never thought about their order. It was the order of the apps that you choose from to be in the panel that appeared random to me. You want to add Astro but its not in the beginning of your list of apps. It could be anywhere and you need to scroll through all your apps to find it. The dev said this is on his list of things to fix so its good to see work continues.
