I did a search and didn't see a thread about this, and I think it's something many people here would really like.
[APP] Nova Launcher Beta (ICS based) - xda-developers've done the launcher foxtrot since getting the GN. I really wanted to love the stock ICS launcher because of all the cool ICS goodies but in the end I had to give the stock launcher up because I hated the search widget taking up space on every screen, I wanted a scrolling dockbar, and really the huge GN screen just screams for a 5x5 layout. So with all that in mind I've used launcherpro, ADW, Go Launcher, and a few others looking for something perfect but in the end none of them had great implementations of ICS. I felt like I was back on gingerbread on my OG. Then I found Nova Launcher on XDA. WOW! If you love ICS and folders and everything else but just want more customization then this is for you. It feels like stock but so much more.
You do not need to be rooted, but if you aren't then you cannot have widget view in the app drawer. That's the only drawback. But if you are rooted then that's not a problem.
