Skada global variables and skinning

[gempir]

Hey guys,

Skada is a big Addon but I can't find any good documentation.

Is there a way to tell if the Skada window is showing, like maybe a boolean?

I found Skada:ToggleWindow(); as a function, but that doesn't help me find out if the Skada window is showing.

Skinning Skada would require similar documentation, is there a way to find important frames or do I have to skim the whole of Skada?
How do most people skin their addons? Like for ElvUI?

thanks for the help guys
