QAbstractItemView::startDrag creates a drag image that is opaque. The user can therefore not see what is below the dragged items and find a suitable drop site easily, in particular if the drag image is large.
Allow the user to specify an opacity for the drag image.
Alternative: make it easier to change the item->drag-image rendering code by making it part of QAIV (protected virtual) instead of the QAIV pimpl.
