Wonderful theme! I am truly grateful.
One thing I have noticed is the menu system functions differently depending on the device.
On desktop, main menu items appear and submenus appear with a mouse hover. On my iphone a "menu" button appears and touching that will open up the entire menu hierarchy, with all submenus expanded. I suppose there's no way around that for the iphone, and it's kinda cool.
The problem is with tablets because you can't hover, but WP isn't recognizing the device as a mobile device and so submenus are inaccessible.
I'll probably try to get around this with separate pages, but I thought I'd see if anyone had any other solutions.
