I'm not understanding why everyone is havaing trouble getting circles to work. All I did was download the apk's from the original thread and loaded them into my "downloads" folder on my SD card. After that I turned on "unknown sources" and then tapped on the apk's to launch the instalers. All went well except the two config files generated an error. Other than that, everything is working fast and great for me. I have fully functioning circles, quick settings, launcher, and favorites.
I had to reboot after installing favorites to get it to expand and now it works great.
...and I am not rooted.
