So the home screen is to be a Floating Rabbit Head waiting for something to do, which makes the most sense for a PA.
But for me to really expand my ability to get organized, I need a visual representation of the storage system. Phones, Tablets, Laptops and Desktops all have a desktop and file System for folders… I am not saying recreate that, but I am saying that I need more.
So since a rabbit can easily fit into a cupboard, why not Shake from the Floating Head Screen and a Cupboard graphic appears and the Cupboard opens.
The cupboard will have shelves. Upon the shelves organized like little teacups will be options; the settings icon, an Apps icon, a Rabbithole icon, and you get the picture… Add your ideas for the shelves in comments.
