One of the most fun things to me is messing around with the Today Screen. My today screen is pretty much a glance of everything I need to know and access in one touch. Or that is what I try to make it which means I have gone through several versions of today screens.
Here is the one that I have had the longest probably.
As you can see it consists of the date, time, a calendar, weather, a web search, appointments, and a shortcut bar. All of these items are available on the Internet for download and also customizable to some degree. I will give credit to FoneJunkie at the XDA-Developer Forum. This screen is a copy of the screen he shared. For details on what each item is click here.
A few days ago I installed SPB Mobile Shell so I have a feeling my screen will be changing. I have toyed around with a few possibilities but haven't gotten it exactly where I want it yet. I'll be sure to share once I do.
