There are two ways to start with the new toolbar:
The first way- Right-click the empty space of the TLB toolbar and select "Close"
 
- Create the new folder where TLB will save shortcuts, menus and settings
 
- Run standalone TLB and select your created folder as the toolbar folder
 
The second way- Right-click the empty space of the TLB Toolbar and select "Open" to open existing toolbar folder
 
- Right-click the empty space of the TLB Toolbar and select "Exit"
 
- Delete all files from the opened toolbar folder. Keep the "User Pinned" folder if this is the standard quick launch folder. Also you can delete *.ini and *.xml files if you have to reset all settings only.
 
- Run Standalone TLB and you'll get the clear/empty toolbar
