I've had GO Launcher EX, LauncherPro Plus and ADW EX installed on my Note...
But I'm using QQ Launcher Pro. Downside is...it doesn't have the widgets that comes with GO, LPP & ADW like messages contacts etc. And it doesn't have many themes like the other Launchers. But thank goodness, the Colorized Widgets works in QQ.
But one good thing about the QQ that it has a widget named "Quick switch" that includes the functionality to lock the Screen.
The best screen effects are (at least for me) Classic (NO rollback) & Cascade.
