Dragging photos into a Collection does not work.

[KeithRJ]

This may have been reported before but I cannot drag and drop photos from a Search or Filter tab into a collection.  The cursor changes into a Pointer with a + indicating you can do this but nothing happens when dropping onto a collection.

Yes, it's a known issue.  You can use contextual menus instead.
