Void Shield Proc

There is now new functionallity to this addon, there is also a settings menu where you can turn off or tweak most things as you please. If you only want the icon it's possible to just remove all other functionallity. 

The White number in the middle of the icon is tracking how many Penance casts are left in the "deck". You can only get 1 proc per 3 casts (per deck). But the deck can have it at the top or bottom so sometimes you will get a proc twice in a row.
The Green and Red numbers track best case vs worst case until you get a new proc.

If you have a proc ready for the next penance cast 100% of the time it will now glow yellow, and green when it's active. 

If the white number went from 1 to 3, and you have a proc active, you can lose procs if you don't hit Void Shield, and due to Blizzard limitations it's impossible to know when that happens, therefore it can sometimes show ?.
