The 'trick' is to do absolutely nothing except size the window, move it where you want it to be, and select the desired item in the sidebar,
then double-click the "||". Now close the window. Actually, you should do this to a brand new window, not one you've been working in. So...
Command-N
Move to desired place on the screen.
Size window.
Select item in sidebar.
Double-click "||".
Command-W.
Command-N to check that it "took".
But, as I said, it only works in Column View. And that view is always alphabetical. If you want stuff in other orders, create some folders for them. A folder name such as "01-2008 Get Rich Plan(s)" will always be at the top of the list in whatever column it appears in. Of course, you can also include days of the month, time, etc. The main thing is to keep the leading zero for any numbers. It's just been a way I've become accustomed to working, different folk like different ways, we can't all be as smart (aleck) as me!
Column view works best with a wide screen, List View probably works better with narrower screens. Icon View is fine if you have only a small number of items, IMHO. Cover Flow is probably a good mix with both List (for sorting) and Icon (visual) displays. It appears, however, that the visual portion of the window has a minimum size. So that would require a larger window to see as much of the list, as in the same sized window, in List View. But 'six of one and a half dozen of the other' is often sufficient!
Since that's only been available in Leopard, many people here won't have much experience with it. How 'bout you trying that view for a while and reporting any pros or cons?
