Battery Doctor does have two Widgets.
One is a Switcher window and the other is a App Closer Widget.
I use both every time I am ready to lock the screen.
Both are shown below
The first one is the Switcher Window where you have instant access to everything that connects to the internet. I turn OFF,
DATA, SYNC, WIFI, Bluetooth
I leave ON the GPS and it is in High Accuracy Mode all the time.
I have determined that the GPS receiver has only about 20 minutes effect on the battery life over two (2) days, so why turn it off? I leave it on so that the camera always can access it for location data. I have the Camera available on the Lockscreen. Use it daily in my job.
At the extreme with light useage, ie, a few telco calls, and a lot of text messaging, I can easily get 4 days between charges by leaving everything turned OFF. None of the stuff that is OFF is needed to call or SMS.
Need to surf the net, or read an email, hit the Switcher Widget and turn on Data or WiFi, whichever is appropriate.
Battery Doctor has a lot of menus to configure, IF, you want it to work in Automatic Mode. You need to check them all out and enable them, or disable them. I have all of the Auto stuff disabled.
I have a Custom Menu and I always use it Manually..... ie, if I am not using the phone, everything is turned OFF.
