The "menu" problem (on mobile) has been a bit trickier. We are getting slightly different behaviour on the different mobile platforms. As of now I have tested it on Android, iOS and Blackberry and it is working consistently across the board. There is still an issue with menu functionality in that if you open a category (ex products), you can't close that category by tapping the "category name'. You need to either select an item in the category or open another category. Will look at this again, but in the meantime it should be functional across most current mobile devices. Let me know what your seeing on your device.
