I think what is meant here is that if the currently focused app/window is Finder, Blurred won't dim the other windows.

Finder is a particularly relevant app to support as often it'll be the focused app but have no window shown which leads you to believe the frontmost visible window is the focused window. This is confusing and frustrating when you try to type or press shortcuts and nothing happens.
