Display suite (http://drupal.org/project/ds) allows you to modify the form display appliyng template layouts. But if i chose (say) a 3 column layout, with say 6 field, the tab order is per column and not per field weight.
example:
left-----middle---right
field1 - field2 -field3
field4 - field5 -field6
if i press tab, the focus shift from field 1 to field 4, and not on field 2 as expected. it's possibile to set a tab order per row and/or per field weight?
