Alexander,
Thanks for the details. Now I see what you’re talking about. Agree, it makes
sense to support this. Could you initiate a dedicated discussion on the dev
list proposing this to the community and sharing design/implementations details
if any? This discussion named “Hello” is not the place for this :)
