[Scribus] Frame sligtly shining through - possible?

[Eilert]

Hi,

I tried to create a textframe over a picture frame. The text frame was 
supposed to be not simply transparent but white and slightly 
transparent, just like you can adjust the menus in some X11 Window managers.

Needless to say, I didn't succeed: Either it was fully transparent or 
completely opaque.

Is this possible to do anyway, or is it still on the wish-list?
