My clairvoyance has been dismal lately, but let me put it to the test here.
Macondo is using VL 7.1 Light, often uses jwm and icewm, and is not using ratpoison as much recently.
Am I right?
So afaik using the window mangager's own tools for this is out, except perhaps for looking into their themes. I tried the edit ~/.gtkrc2.0 thing -- nogo with icewmvmods. So I'm thinking wm theme for that.
