Option to hidden frames
I don't know if it's possible, cause I cannot understand if all the lines I don't like, belong to GtkFrame widgets. If it's so, it should be sufficient to add an option in the engine to set GtkFrame::shadow-type = GTK_SHADOW_NONE.
I add an image showing what's the situation now and a mockup of what I would, in thunar and medit
P.S.
If there's a simple solution, Cimi, you can reply to me here
