How about don't seed while using battery/not plugged into the mains option?

[Eggburt]

Hey,

I was wondering if you could add a feature for laptops where it doesn't seed while using the battery?

I know I have the option to turn µTorrent off,  and I frequently do while trying to get a whole film out of laptop on battery, but I often forget and then have to rush around looking for a charger.

Any chance you can add his feature to the next update, or just tell me it's already a feature and I just need to update etc?
