!BeautyCase help

[Viridis]

I love this little addon and I'm currently starting to add borders with it to various frames, however when adding it to sThreatMeter2 the border remains even when the actual meter is not in use, is there any way to make it disappear with the threat meter?

I was also wondering if there was a way to add the lines such as;
CreateBorder(sThreatMeter, 12, 7, 7, 7, 1, 2, 1, 2, 1, 48, 1, 48)
into their own addon so that I can update addons without having to keep re-editing.

My last question is whether I can use BeautyCase to skin the default buff frames? I tried using the frame "BuffButton1".

Thanks for any help in advance, I'm completely new to any kind of lua editing.
