Yes, most trivial, just adding all available styles to the "View" menu 
(with "Grid layout" now becoming one of potentially many options).

Yes, I'm also concerned when people speak of copying elements from one 
layer to another, I don't think the mechanism is quite fit for that. 
That's why I wanted to have all objects in the same layer (they are 
interconnected anyway!) and just "shine different lights" on them.
