Do I recall correctly that in the recent hacks people have reported that the flow had dodgy flow inserted well down the page and stacked as above in order to hide itself a bit ?
Learnt something new: yammer being MS corporate social media platform - I did not know!
And I thought it was Jammer... Since there's a german word jammen which means to complain. Perhaps MS meant to aim yammer at the german market. Would fit very well.
I realised that putting all nodes on top each other isn't a problem since there's an auto layout node... But hey, it's the thought that counts - as the germans say.
