Another little (?) wish: Double clicking on a part in parts bin currently replaces selected part. Good thing... But I'd like (when no part is selected) this double click to create a new part placed and oriented like the last selected one. This would help with parts with no connectivity, we would start in a known place then use move/rotate tools. Dragging a new part from parts bin is not so convenient, especially when using a fine grid. On a new model/submodel (thus with no previous part selected) the new part would be created at origin with default orientation.
And probably pressing insert while hovering over parts bin should do the same as double click.
