Not rooted and I use Elixir2, works great.
For those asking. Elixir is a widget tool, once you download it you add a widget"s" to the homescreen. Elixir allows you to add a "bar" with multiple widgets, short cuts etc. on it. That bar can be 1 single widget or a 3x1, 5x1, 1x3 etc. I use: Battery level, battery temp, Wi-Fi toggle, Wi-Fi hotspot toggle and a shortcut to my camera on a 1x3 bar. You can totally customize the size of the bar and the size, color, transparency of the widgets on it. I make mine small so all 5 fit on 1 bar. Also, once you create a widget you can go back into Elixir and customize any you have already created.
For the Wi-Fi tether you still need to go into the default program and set the information but once you do, it works great. Settings > More > Tethering and portable hotspot > Configure Wi-Fi hotspot.
I prefer Elixir over the other ones mentioned because it has a ton of other useful stuff and it's very lightweight, battery wise. Also, it doesn't seem to mess up my signal when it's deactivated like so many others do.
