I agree that the notification bar is WAY too busy. It's annoying because precious space is taken up by these icons, and only fewer icons from actual notifications are able to be displayed.
Here's my list of suggestions (in case someone who can do anything about these happens to read this thread...hint hint). This is on a Verizon G2:
1) Option to turn off the location access icon. This one is just annoying and for me completely useless. I always have location access turned on. So this icon doesn't tell me anything. And if I do decide to disable location access, a different icons is used instead! There is no way to get rid of this icon! AGH! Honestly, if I do decide to root my phone, this currently is at the top of the list of my reasons why
2) Option to show just battery % without battery icon. I want to see the %, and the batter icon is completely useless and takes up space
3) Option to turn off 4G/3G/1X icon when using WiFi (or when using WiFi, move 4G/3G/1X to the left upper corner of the signal bars). I'd prefer to be able to glance at the screen and see what I am using for data (and seeing both WiFi and 4G are annoying)
4) Option to not display icons when in Silent or Vibrate mode. This one doesn't bother me as much as the other 3, but it still adds clutter. In the interests of customization, I could also see some people wanting an option to always display an icon for the mode (Silent, Vibrate, AND Sound).
