Standalone Toolbar as contents of folder

This is perfect, thank you! Where are the same auto-hide options such as animation effect/speed, etc for this torn off menu?

TLB Settings->Menu->Docked.

Also, the customize menu, adding a docked customization doesn't seem to have any effect...

This is confusing a bit, I know. But if you want to customize the docked menu, just right-click inside this menu and select "Customize menu". If you have some docked menus and you want to customize them all, the "docked menu level" must be added to the parent of all menu. The best way: right-click the toolbar and add docked menu options there. Toolbar is the parent of all menus (root).
