Perhaps this article elsewhere has at least a partial solution to the autosorting problem.

@xpclient: Please test it and let us all know whether it solves it.

I see a previous suggestion of using alternate file managers but I'll also add that xplorer2 has this behavior as a toggle-able feature.

@dencorso, that fixes it for icon-based views (Large icons, Medium icons, Tiles etc) and it looks like you can freely arrange in Details view as well. Only view that remains is List View (which is the view I prefer). Auto sorting remains on List View. Paste multiple files and they get scattered, create a folder and it jumps to the Ns, rename any file and it jumps to obey the sort order.
