Hi, due to limitations of the WP7 OS, we don't have direct access to most of the settings, phone hub, people hub, messaging hub, or email hub. If and when MS gives developers access, our app will support them.
Also, we don't have access to double-sized tiles or other Apps like calculator.
Not sure what you mean about different address to an existing tile.
Very very nice app. One of the best skin customization apps I've seen so far, probably the best there is.
It's too bad that MS doesn't let you allow to edit the basic hubs. It would be nice to completely remove the stock Hubs and replace them with the self created ones with this app.
