I've got absolutely no clue how to make an app. But I just got this idea... This app is supposed to dissable all non criticall functions of the tablet in order to increase battery life, in case the user is going to town for more than 24 hours. What if someone created an app that would do a lot of different power related things. Some of these things should be to unload the wifi part from the kernel, put screen brightness to the lowest level possible, perhaps forcing the cpu to run 250 mhz only, dissable vibration and notification light... All this should happen at just one press of a button... and pressing the button again should put things back to the way they were before. Of course all this can be done manually but its a lot of buttons to press in order to dissable and then enable all of these features again. What is your comments about an app like this?
