Don't mean to hijack this thread with my own ideas, but I saw your concepts and ideas started spinning in my head... Here goes.
Now, after playing with this concept, I was thinking... IntelliScreen has the weather, which I think is pretty cool. But there isn't really any space left, unless we totally redesign the layout. That could work better, but for now this is what I've come up with.
The Weather and Calendar bars are little mini widgets I guess you could call them. The bottom slot could be filled with any number of these little guys for anything and everything. Any type of information could have it's own mini widget.
Now the next step logically is to ask, could every bar just become a mini widget. Could the calls, sms, calendar, mail, weather occupy maybe 3 thicker mini widget styled bars, that could slide to reveal information, as opposed to just sliding to open the actual app. I guess those are the two different directions this app can take. Shortcut vs. actual information display right on unlock.
Let me know what you guys think..
