So, if i get a handle on the castbar via frame:GetChildren(), i should be able to get to the 2 new regions via GetRegions().
Example:
Code:
cb.texture, cb.border, cb.shield, cb.icon, cb.shadow, cb.name = cb:GetRegions()
Am i right?
EDIT: my addon works correctly - i assume that not managing the two new regions will make the game automatically display the standard ones.
