Reorder Login Items via drag and drop

Here is a way to re-order the login items in your user's Accounts System Preferences panel. (Whether this is actually useful, as those items now load asynchronously, is another question entirely.) 

Click and hold on a login item, and drag the item a little bit down and/or right. Notice that a dark line will appear at the bottom of the list of items in the login panel. Release the mouse button, and that item will be moved to the bottom of the list. Not as convenient as "drop to the location of your choice," of course, but with a modicum of planning, you can re-order your list this way.
