First, thanks for the great application! Before Curtains (well, and WindowBlinds), a lot of us were using a kinda sketchy application and themes we'd download off a website to theme our windows. This broke my OS often enough that I eventually got sick of having to reinstall Windows and just quit.
But one feature this application offered that I don't see in Curtains was the ability to separately theme Explorer's Navigation Pane, which could result in some pretty nice themes, like the following:
Any chance this could be implemented in Curtains?
Another feature request: would it be possible to apply the theme to inactive windows? Or does this option already exist and I just can't find it? I'd love to be able to slightly dim the inactive windows (which I think I can do through WindowFX) but have them retain their Curtains style.
