I do see the customizable settings. However, it seems to me that I am defeating the purpose of even having this program in the first place as I have disabled anything that turns off my phone's radios (WiFi, Cell Service, Bluetooth), which are the biggest battery drainers.
Am I getting text messages with it running? Can't say as the phone is new and since installing Juice Defender two days ago, there haven't been any.
However, on default settings, all my radios would turn off once I put the phone in my pocket.
