No there isn't. The launcher was used until Amnix went back to touchwiz. I like the both launchers and tried and tested both, and thought what an incredibly nice guy I would be if I threw it up on the forum for others to use. It's main difference is allowing to resize ALL widgets. It isnt a battery killer.
This tells me you haven't read the thread. Reading is fundamental. Not only is it in the OP but there are a couple times it is mentioned in the thread. Read the threads. People don't do that. You didn't either. Otherwise you wouldn't have asked.
Here is my basic rule on installing a new ROM. After initial reboot, reboot again (as mentioned in the OP). I take it one step further. I wont touch my phone for 30 mins or so, to let everything settle, at which time I reboot again. After that, I will stress (max settings, wifi, data, gps, brightness at 100%, etc,) my phone until the battery is between 10-20%, typically closer to 10%. I power down the phone and charge to 100%. After that, I use it as normal.
Now, with v0,98 I was seeing insane battery life. Sometimes going 3, yes 3 days before it would hit 10%. Side note, never charge your battery until it goes below 20%. You will be surprised doing this one thing will increase your battery life. v2.1 was a little marginal on battery life but still getting me through a day. v3.2 is back to insane battery life. Since I installed this last week, my battery life has averaged roughly 33-38 hours, this with wifi or data running quite a bit, playing games, etc , or what I call my typical use. Hope this helps.
