Ive searched for this but either Im not wording it right or Im blind so please if this is discussed somewhere forgive me.

Anywho, is there the ability or a tweak that when an app is loading and you get your themes loading wallpaper to have a loading bar on that wallpaper?

Kinda like this:

I want to try and add something like that to the boss.ios theme.
