I support IOhannes' idea of distinguishing between opening from the menu and opening from the OS file system, and of asking the user if they want a new instance.

Another case for multiple patches is this: the user is editing a patch, but worries that he has misplaced a connection or damaged it somehow. So before saving it, he opens the earlier version from the menu, just to check that everything is in place. Then he closes the old version and saves the new one. I find myself doing this a lot, and it doesn't seem particularly "expert" to me.

Having said this, I think the new feature is worth keeping, so long as there is some provision for multiple instances of the same patch.

Ah, yes, a fourth option: have a new "pd really-open" message to open
a file without checking if it's a duplicate.
