Yes, but there is still no bookmark manager. Try to create (on OS X) a bookmarks folder in the bookmarks bar. Proceed to add two bookmarks into that folder. Now... How do you edit/delete/rearrange the bookmarks that reside in the folder? I can't figure it out.
Here's what I did (on OS 10.6).
1) Created two bookmark folders in the bookmark bar named "NewFolder", and "OtherFolder" (right click on bar->Add Folder)
2) Added two bookmarks to NewFolder (browse to site, click star, select NewFolder in Folder drop down list)
3) Moved bookmarks from one folder to the other (browse to bookmarked page, click the star, click Edit, change the folder drop down selection, close)
This doesn't allow you to move folders around, and it's annoying that you don't have a way to manage the bookmark of a page without browsing to that page. It's not the full "Bookmark Manager", but you can manage bookmarks.
