Comment 17 for bug 171944

As a casual user I preferred the (more) predictable results of the previous version (exchange-positions-2.diff).

1) selecting a horizontal row of elements (by dragging a selection window or selecting them individually) seems unpredictable with 'exchange-positions-3' and does not always return to the initial sort order after a 'round-trip' (test case used: 171944-shuffle2.svg, objects on layer 'vertical').
'exchange-positions-2' exchanged the selected objects according to z-order (when selected w/ dragging a selection window) by moving the first object to the last position and shifting the other objects one position up. With the new version I have a hard time detecting a logic in the way linear arranged objects change their position.

2) Exchanging multiple selected elements that are arranged around a center (objects on layer 'spiral up/down', 'circle') seems to give the same and predictable results as in 'exchange-positions-2'.
