One more suggestion: Make the list order customizable by user. That is, have some default, for new users or users not logged in but viewing a public group, and allow the user to change the list order. The same order would apply to all of the user's groups where the options are available. If a new feature is added, it can default to near the top or near the bottom of the list, depending on how much you want to promote the feature.
