Not sure how to make it more prominent - did you search for it at all? where?

Yes, this would indeed merge the winprops - thanks for diving in.

Still, we should carefully consider a couple things:
- Language power: I think we have established that this approach allows us to
  neatly express some configurations that we couldn't express with the old 
  semantics. Can we also think of configurations that could be expressed in 
  the old semantics but not in the new ones? Can we do anything about those?
- When defining more and more rules, does the configuration remain readable
  (and thus maintainable)? Will unexpected side-effects lead to confusion?
- Can we think of a way to introduce this without breaking the carefully-
  constructed winprop configurations of our current users (and all ion3 
  users)?


Kind regards,
