I found putting a number in front of the filename moves it to the top. However, this isn't great when the filenames already start with a number. But I guess it will have to do.
My version of Nautilus (2.16.1) doesn't have View > Arrange Items. (I usually run in Edgy since I find it more stable then Feisty.) I'll have to boot to Feisty to see if it has a different version that has that option. Thanks!
