Screen Dimmer App for TP2

[badsez]

I hate that the screen is bright and wasting precious juice while not being used. Installed nuebattery app to control the screen turn off settings.
But i have a further requirement.

Looking for an App that can turn off the screen if it hasn't been touched for a minute but not turn off the device. Also dont turn off the screen if a video is being played.

There used to be a screen dimmer app called candle light in Moto Q. wonderful app.

Hope there is an App for my requirement.

One scenario: I use wifirouter to connect to the laptop. So..i really dont need the phone's screen wasting away while i'm working on the laptop, but if i turn off the thing with the switch on the top.. i guess the device sleeps and i get disconnected. I wish there is a way to keep wifi active while device is turned off on a selective basis.
