Power Meter Plus

Replace the native battery power meter for Windows with a better one! Power Meter Plus has the following features: it gradually appears as the power levels drop; the lower the power, the more prominent the meter will be; when you're charging the laptop, it'll turn green and slowly disappear/fade as the charge increases. The meter appears either on the bottom left or bottom right of the screen and it moves to the opposite corner if you move your mouse over it. Neat!
