Translucent sidebar in El Capitan?


If you be great if we could create a theme with sidebar translucency, such as in some native apps an finder. Here is OmniFocus 2 with it’s “dark” theme.

NOTE: I’ve read threads on full transparency, and that’s not what I mean. Note in OmniFocus the window and content area are opaque; their dark theme just allows translucency in the sidebar.


But that is where things would have to start. The window itself would have to be transparent and then selective areas would be occluded to some level to create the translucency look. Other areas would be completely opaque.


True. I just wanted to clarify, since most of the other thread was people who wanted their whole app to be transparent. But I understand what you mean.
