Does what it says on the tin so to speak, 5/5.

My only minor complaint is that it would be nice to just be able to click the percentage value and input a number via numpad instead of using the slider.

Maybe it's just my obsessive need for a perfect 100-value, but it would be easier to just press 3-0-0 + Enter than it currently is to use the slider to find 300% since it doesn't update the number until you let go of the slider.

Alternatively if the percentage did indeed update during the time you adjust the slider, that would be almost as good.

Ideally I would love if the addon had both of the above features :)

Just a tip/idea Mr. Developer :)
