@JuliaSprenger do you plan this for 0.7 ?

[JuliaSprenger]

I won't have time to work on this in the coming days. If anybody feels bored you can take over. Otherwise we have to postpone this. Sorry :/

@JuliaSprenger, @apdavison, Doesn't #668 implement all the intended changes?

[JuliaSprenger]

I checked #668 and this covers all the cases I had in mind for this PR. So I will close this one now.
