Standalone Toolbar as contents of folder

I've tried this sort of thing before with a tear off menu, but going that route doesn't seem to have any ability to 'dock or auto-hide, etc.'

This is the right way! To dock the torn off menu, hold down the CTRL key and move to the menu to the screen side. TLB will dock menu automatically. The right-click the menu for auto-hide options. Here is video about this feature: http://youtu.be/2MSoC3dZl48

Also the version 6.6.9 RC2 have the tags for the docked menus.
