I merged your post with the appropriate thread. Please see above for instructions on how to recreate the folder and let me know if you have any additional questions!
You are correct. The "Unfiled" Smart Folder was previously included by default and non-removable. Many users found it confusing, so we removed it. To recreate it, select "New Smart Folder" form the File menu.
New logins are not saved in any folder. They should now show up in the "Unfiled" Smart Folder you created since they will not be filed in any folder when they are first created. They will also show up in the "Logins" vault.

That's very helpful!
Even so, I suggest adding an option in preferences with a checkbox for having an "unfiled" smart folder. I've always found it indispensable for locating recently saved logins that I hadn't yet filed in a specific folder. I'm guessing a lot more users who really want the function would find it in preferences than would happen on "smart folders" and instructions like these about how to create it manually.
(I would even make the box checked as the default, but that's probably a religious war in the making...)
