1) All packages should have SSL. I don't do business with companies that think security is an optional feature.
2) Single sign-on should be available for all packages. I am not interested in a walled garden approach for my app's support.
3) I don't care about white labeling, but a custom design is extremely important to me. Support is too important for our growth to just throw our brand out the window. Any support system needs to be contained in my website's frame.
That said the app looks really nice. A demo would go a long way to giving me a sense of the user's experience because as it is I don't know what 1/2 of the features are and how they are accessed.
