I use Bartender4 for my actionbars and had a question about fading.

Is it possible to:

a) Set an inhernet opacity to the bars (i use 3) while IN COMBAT and then;
b) Have them fade almost all the way out when OOC.

I feel like this should be easy but when i tried it it ended up being mouse-over and stupid...

I'll post my UI when I get home from work too as I would like some cc on it.
