-------------------------------------------
[~chesnay] This ticket mostly relates to user-perspective testing of the whole
feature. So the main target is to look over documentation then try the feature
and give some feedback. Also, the best person for this ticket is somebody who
didn't take a part in the implementation of this feature.
