I noticed in Curtains that none of the styles seem to affect MDI windows.  Is this possible in some way I haven't figured out?

I understand Curtains works differently from WB (where it does work) and it might not be possible, or it could be a v2 feature, but speaking for myself, I certainly am quite tired of the not-so-appealing basic/aero lite theme on MDI windows. 

In the past there have been some great themes/styles (both for WB and without) that have made MDI windows look far more appealing, but there are a lot of drawbacks by using those methods of theming that don't exist with Curtains, which is part of the appeal.
