I'm able to add new popup menues and so on.
Also I'm able to add user custom Buttons, but only to existing Button-Toolbars!
Set Button1 = CommandBars("Standard").Add(cmdControlButton,,,-1)
here you see my example user button "Readme Datei" - but in the "Standard" Toolbar! ...
...how to create with Automation a new own Button Toolbar?
(for where I can add my Custom Buttons)
