1 & 2 are both in Leopard. Apple ditched the weird Spotlight results window in equally weird but more functional views in Finder windows. 4 is in Snow Leopard.
Sorry about that - you're right about the deleting and copying in Leopard. As with the Finder in general, files cannot be cut/moved, and renaming is not available from the Context Menu or by pressing Enter (though it is available by clicking the file names).
As for #2 ("In Folder" or "Location" column in Spotlight results), can you please tell me how to display such a column?
