the problem is, i only have one spot for an icon on my home page, and i want both things (speakerphone and screen on) to toggle. so i need a single widget that handles multi functions.
and i found it! setting profiles lite. it allows you to have a single widget which toggles tons of things, fully customizable. it actually allows you to set different profiles, all with their own settings, but the free version only allows you to set one profile. however, since i only need a profile for my car, that works for me. you press the widget icon, which brings up the "list" of profiles (just the one) and then you click that. same procedure to disable. so it's actually two clicks, but it's just a single icon space, so that works for me.
so if anyone else is looking for this type of thing, where you only have a single spot but you want it to toggle many things simultaneously, try this app.
