>I hope you will have an option to disable this News Feed and bring the right-side pane just like it was. I find this UI approach very unhelpful.

We are still working on that. As I said, we have collected the feedback and some of them are leading towards our objectives but some things have to change. There has to be a context of social network, and there are various reasons for that, such as the viability of the product, in preparation of the mobile app, and so on. So, yes, they will be changes. But, all fonctionalities will be preserved, whereas, maybe, some of them would be accesssed in a different way.

Thanks for the feedback
