It'd be nice to be able to use gpstoggle without the traditional today screen.... Although I could actually use it when I used SPB MS3... But that's because I didn't use the widgets. I liked having a condensed version of the Today screen that I could jump to with a couple of things on it to use a shortcuts and of course to turn on gpstoggle when needed and then jump back to MS3 leaving those programs to run in background... but I don't know of any other way to make the program work
I am using 6.5 right now so I don't even have the option to turn it on and leave it in background, but now that I can customize the panels, Titanium > regular today screen
