What exactly about Touchwiz are you finding annoying? Asking because maybe you don't need to root, just try a third party launcher?
For the most part I like TouchWiz. However, I find it frustrating that I can't configure it without replacing the rom.
You didn't ask me but here are the things I miss from AOKP on my Galaxy Nexus:
Notification shade:
- The TouchWiz toggles are WAY TOO BIG. I don't really like toggles in my notification shade but if I do I prefer small icons
- I certainly would put a wifi toggle in there, something Verizon doesn't permit
- I want screen brightness control in the shade but not visible. In AOKP I can just pull down the shade a half inch and slide my finger to the right or left to change brightness.
- I don't want a notification of which wifi I'm connect to. If I want to know I'll look.
Other:
- I'd turn off that eye in the notification bar. I still want the Smart Stay feature turned on, I just don't want the eye taking up precious real estate.
- I want battery % without the green battery icon.
- Full rotation in any direction on any screen including the pattern lock screen. (Of course with a "hard" home button this would be less useful on the Note 2)
