Back when I was using an IPaq, you could choose different time settings for the screen based on whether you were on battery or AC adapter. I use my Droid 2 at work for music and would like it to always be on while I have it plugged in, without having to go into settings each time I plug or unplug it. I get tireed of unlocking it every time I want to choose a new song or check the news. I haven't been able to find an app that does this. Does anyone know of one?
