To me it seems more logical to have new items been added to the end of the backlog. This instead of the current behavior of adding them at the top.
We try to keep the top of the backlog groomed, and if just before starting a new sprint the top of the backlog is polluted with newly added items this is pretty annoying.
Maybe I am missing a setting? And if not, could I suggest a feature that this behavior can be influenced with a setting per board?
