Ok, but what happens if you label a small button with more letters than its size "allows"? Does it change size or will it deny any letters above a certain amount.
If you take an empty template (no matter what device) are the amount and size of the buttons predefined, so you may either have a site with 15 small buttons or a screen with fewer but bigger buttons?
I hope one will be able to design all templates from a "clean slate" as you call it. It would make it easy to use it activity based like the Take Control is, which sounds very sensible to me.
