How to Find Truly Hidden Toolbars

All toolbars for Standalone TLB are listed in this file:
%appdata%\Tordex\True Launch Bar\standalone.xml

Exit Standalone TLB before editing this file (right-click the empty space of toolbar and select "Exit")

Use editor that can reformat XML to make it easy to edit. I recommend Notepad++ with XML Tools plugin.

Every toolbar is defined in <toolbar> tag. So if you delete it, the toolbar will be deleted.
