There is currently no way to move or rearrange rows on shared filters New rows can only be inserted as the last row and cannot be moved up.
This is a problem if you need to insert a new row in a particular spot in a filter. For example, consider the following situation:
(row 1 OR
row 2) AND
row 3 AND
If you want to insert an additional row into the OR condition (above row 3), you would have to delete rows 3 and 4, then add your new row and then add rows 3 and 4 back in. If rows could be moved, either with up and down arrows or with drag and drop, it would be much easier and faster to make such a change.
